  1. A couple of months ago I decided to have a crack at writing a new BIOS for Ultimate 1MB from scratch. Its purpose was simply to facilitate a bootable version of the WIP Graphical OS in ROM and add some extra PBI BIOS options, but the project quickly ran away with itself and became an exercise in completely re-thinking just about every part of the functionality. The new BIOS offers: The ability to set the date and time from the setup menu Dual configuration profiles Categorized menus covering system settings, hard disk, device setup, etc Turbo-Freezer compatibility Customisable shortcut keys OS-independent Ultra-speed SIO for serial disk drives Optional BIOS logo screen and boot device selection menu Optional flash write protection System information page displaying CPU type, audio/video hardware, etc BIOS Plugin API for diverse hardware control (Ultimate 1MB only) Variable SpartaDOS X ROM sizes (192, 256 and 320KB), and the ability to boot the WIP Graphical OS (when 192KB SDX is used) So this is a beta version of the new (alt) Ultimate BIOS, provided with a new (beta) version of uFlash which is designed to handle both original and new BIOS versions (and the upgrade process), a (required) PBI BIOS update, and some documentation. I've also thrown in a complete Ultimate 1MB ROM with the GOS intended for testing in Altirra (or on a real machine if you're feeling brave). Ultimate BIOS Beta 0.24 Release.zip You'll notice the word 'beta' crops up a lot. This is BETA software, so please ensure you have a means of recovery in the event something goes wrong with the BIOS flash, or something unexpected goes wrong with the BIOS. Although the last couple of builds have been well tested, it's a BIOS and is therefore critical to whether your machine boots up or not. I can't stress this enough, and I do not want to hear people complaining about bricking their machines and having no way to recover. A USB flash ROM programmer is an absolute must if you want to test this on real hardware. The sensible procedure is to back up your entire Ultimate 1MB ROM first so that you can go back to it if you need to or if you simply don't like what you end up with. You can do this in-situ with uFlash or with your USB programmer. The (draft) documentation outlines the upgrade procedure, and you must upgrade both the main BIOS and the PBI BIOS both at once. That means load up uFlash, flash BIOS24.ROM to the "BIOS" slot and ULTPBI13.ROM to the "PBI BIOS" slot. Then do a power-cycle. The NVRAM configuration data of the original BIOS is completely incompatible with the new one, so although your system clock should remain valid, nothing else will. You'll be prompted to set things up again after the upgrade. The defaults chosen (i.e. stock RAM) will be subject to change in the final version, as will anything else I feel like changing, although the OS ROM, BASIC and XEGS slot descriptions (which should survive the upgrade) won't change position again. Things that don't work or only work partially or don't work at all: Boot device menu: works, but isn't finished "Redirect D1:" in the PBI BIOS menu is not implemented yet Other stuff This became such a gargantuan task that I just want to leave the beta out for a week or two and do other things to get over it, before fixing what needs fixed and getting on with the new (alt) XEX loader, which is about half done but will take a while to complete. Lastly, I want to offer massive thanks to Phaeron, Hias and Prowizard. The assistance they have provided in terms of testing, ideas, and technical insight was really fantastic, and without them, some of the neat features present just wouldn't exist at all. And had Hias not kindly agreed to let me use his High-Speed SIO code in the PBI BIOS (more or less verbatim), there'd be no High-Speed SIO. Thanks also to MrFish for valuable feedback and ideas on the UI, and of course to Candle himself for the hardware and original firmware. The sole purpose of this new, alternative BIOS is to get even more functionality from this fantastic hardware, taking inspiration from his initial achievements. I've probably forgotten stuff, but it's late, so - enjoy. PS: Incognito BIOS to follow shortly.
  2. Hello everyone, I finally got around to installing my Incognito board with the help of a local hardware guru. I had purchased a refurbished Atari 800 from B&C a while back which worked great and was hoping to "upgrade" it with this board. However, we ran into two questions that I'm hoping someone here might be able to help me with. #1 - It turns out I have a different CPU board than the one shown on Candle's install guide. Here it is: and Does anybody know where to connect the two (yellow, green) wires shown in Candle's instructions on this version of the CPU board? I'm game to buy the version shown if I can be sure it will work with the rest of the computer. However, it seemed worth asking here first. #2 - It looks like the ribbon cable I received has the connector that plugs into the motherboard mounted backwards as compared to Candle's photos. When aligned as shown in Candle's photos the red line is on the right and not the left. However, the connector that plugs into the Incognito board is aligned as shown . I can upload pictures if necessary, but this one seems very straightforward. My friend thought I could just rotate the connector with the pins 180 degrees when plugging it in but suggested checking first. Can I do this or do I need to find a way to reattach the connector? If the latter, any suggestions would be appreciated as my friend wasn't sure he had the right tools for this type of connector. Many thanks in advance for any help. Also, a big thank you to Candle for making this board happen! -Jason
  3. Hi all, Now my 1200XL has had it's Ultimate 1MB fitted my 800 with Incognito is now for sale. It's a PAL machine with the latest firmware, in excellent condition bar a small (and I mean small) nick in the top cover as seen in the last photo. Absolute beauty with no yellowing, supplied as bare machine as I'm sure you'll have your own power supply and monitor cable I will include the 1GB CF card, full of Atari goodness! Price for AA members is £200 GBP plus postage if needed (I'm in the United Kingdom), I will ship anywhere in the world, as long as you pay the postage and any customs charges! If you want any more pictures or have any questions please ask. Thanks to you for looking and thanks to AA for use of the site. Cheers Dom
  4. Shouting from the rooftops for a fourth run of Incognito's. Oh, Candle... Hear our prayer.
  5. OMG this is frustrating .. I have installed my Incognito, and as far as I can tell it seems to be working.... BUT.. I cannot get SDX (I dont know another OS for this) to read the FAT16 partition on the CF card. The cf card is a 8gb sandisk Ultra - BIOS (FJC latest) reads card.. Fdisk inits it, partitions it.. I can put in in a PC and format the Fat16 I get all OKs on the chkfat. The partition seems fine. APT partitions I can build directories, I can transfer files etc.. no issues - it seems to be just the FAT16 - In the BIOS SIDE LOADER - I can see the FAT16 partition fine. FJC has loaded this CF image into Altirra and it works fine (Image is available for anyone) BUT - if I just load SDX 4.47 from the incognito, (I am waiting for a 192k GUI friendly size 448) .. I get 148 unknown file system (SO?? is Fatfs.sys loading from 447?? FJC works on Altirra?) IF I run fatfs.sys from the 4.48 toolkit.. and try and dir d3: the system locks up - I can do nothing.. but after reset (not cold - so 448 fatfs.sys is still in there) I run dir again - I get 181 file system corrupt.. I can run a chkdisk on it.. but nothing else. FJC and I have tried as much as we can see .. he thinks hardware... I really dont have and idea.. Any one know enough.. Could one of the wires that are specific to PBI function on the build be an issue?? Looking for ideas please!!! James
  6. I am attempting to create a simple IDE/CF interface for the 1088XEL's MPBI port (Mini-Parallel Bus Interface). The idea is to have it be supported by the U1MB BIOS in some fashion that is similar to the Side2 cart, but without all the bells and whistles this cart has (sans SDX and R-Time8). So to do this, it appears that loading the Incognito PBI BIOS into the U1MB might give us a simple software solution, since it only requires that the 8 basic IDE registers be accessed and mapped into the appropriate area (see FJC's comment below quoted from an earlier discussion Link Here) So my plan is to modify the original MyIDE ][ internal interface circuit as shown in Mr Atari's site (reference), and do some extra decoding to make it point the IDE registers directly at $D1E0-7. Below you will see my first proposed design to hopefully accomplish this. Here's the complete MPBI port as it is implemented on the V1.1 XEL... I plan to use one of these CF-to-IDE adapters while prototyping... Although the preliminary schematic doesn't show it, there will be a MPBI pass-thru provided as well. - Michael
  7. Please find a major update to the APT soft-drivers, PBI BIOSes, and partitioning and hard disk management tools here: http://atari8.co.uk/apt/ All drivers are updated, with brand new tools provided on customised SDX 4.46 builds and an APT Toolkit ATR if you prefer to run them from disk or with another DOS. Existing tools like FDISK have been heavily revised, while most other tools are brand new. The tools are: FDISK MATR APTDISK APTDEV ATRMNT MOUNT CHECKAPT UFLASH General documentation is provided in PDFs, while detailed coverage is included in text files on the toolkit ATR, which also includes all the soft-drivers and both PBI ROMs. SDX soft-drivers (pre-installed on custom SDX ROMs) are provided for the following hardware: MyIDE / MyIDE+Flash MyIDE 2 SIDE SIDE2 Colleen Most important, perhaps, are the major updates to the Ultimate 1MB and Incognito PBI BIOSes. These updates provide very greatly improved compatibility with SpartaDOS 3.x, MyDOS, RealDOS, as well as many, many ATR-based game titles and demos. Non-standard ATRs are now supported, and a raft of efficiency and stability improvements have been made. Several bugs have been fixed, and useful new enhancements implemented. See the BIOS changelog for details. I won't say too much more, since it's getting late and preparing these updates has taken almost a month of intensive work. I must express my thanks to AA member ProWizard for inspiring the recent frenzy of development and assisting me so ably and generously via testing and bug reports. Thanks also to Candle for his work on the latest SIDE loader and his provision for UFLASH support direct from FAT32. If you find bugs, experience issues or just discover broken links, etc, please let me know and I'll fix anything as soon as possible. There is such a lot of material here that I could hardly expect perfection, but at least I guarantee any problems will now be easy to rectify and probably caused by my own stupidity or tiredness. Ultimate and Incognito users my simply want to flash the PBI BIOS update and SDX 4.46 build and then read the manuals later on. PS: IDEa BIOS to follow... just ran out of time and steam tonight.
  8. Hello, I bought this board recently but after thinking about it I changed my mind and I do not want to modify my Atari 800. So there's no point in holding onto this. It might as well go to someone who will actually use it. I have put it on sale on EBay for more than I paid because eBay charges a big chunk in fee's and I don't want to lose any money just break even. I can sell it cheaper privately. You can PM me directly if interested. Thanks http://www.ebay.com/itm/172093533916?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
  9. This doesn't really fit anywhere else, since several hard disk interfaces are using APT these days, so I'm giving it its own topic. Following some helpful suggestions regarding the APT Partition Editor (FDISK: thanks Marius and others), I've been doing some significant revisions on that program, aimed both improving usability, and paving the way for some cool future enhancements to the way we move data around. While looking for inspiration for the new FDISK's UI improvements, I found myself (re)reading DrCoolZic's excellent UltraSatan manual, and noticed something I hadn't seen before: namely where he talks (in Chapter 4) about a driver which allows the use of partitioned removable media in Windows. Now, Linux has always been able to do this (AFAIK), and GPARTED will partition CF and SD cards without issue. But while one may use third-party partitioning applications in Windows to partition removable media, Windows won't mount those partitions when you put the card in the reader. However, DrCoolZic's method appears to circumvent that problem, and I'm now able to use the Windows 7 Computer management console to partition CF cards. What's this got to do with APT? Well - maybe you want three FAT partitions on your SIDE CF card, as well as APT partitions that the Atari file system can see. FDISK doesn't provide an MBR partition editor: it just asks some simple questions about how you want to chop up the media between FAT and APT. And - while the new version of FDISK will be more flexible in this respect - it still won't provide a full-blown MBR partition editor. What it will do is allow you to tag an APT onto the end of a pre-partitioned card, or even assign an existing MBR partition entry as an APT area. Anyway - I've just started playing with these removable media drivers, but I thought I'd share. Here's the info: http://www.atari8.co...gRemovableMedia
  10. Hi, yesterday I´ve found an interesting thing, which I didn´t know until now. On pin "S" of the cartridge-slots of an Atari 800 there´s not the "PHI2" signal attached as on all newer machines - there´s "RAS" connected. The falling edge of PHI2 and RAS is nearly the same, but RAS is much shorter low than PHI2 (of course, there must be some time for CAS, too). Most modern circuits (in flash-carts or flashable carts) sample the PHI2 signal for their logic. So I think, this might be most significant reason for problems while writing to flash-memory or using special carts like the myIDE II. See the signals on the scope: So I try a little modification and use PHI2 on pin "S" instead of RAS. And these seems to be the solution... myIDE-II works now without any issues in an Atari 800 with Incognito. Also some other carts with suspicious failures works now. I test this on two Atari 800 equipped with Incognito. On one machine I take the Incognito out and re-install the old genuine personaliy and RAM cards. Also everything works fine. I have only one cartridge with "Write to cart" features which works on the original old 800 system: Telelink II. But this also works fine with that patch. If you want to do this patch by yourself, here´s a possible way: Cut the RAS trace on the place in the picture. Connect pin "A" and pin "S" on the "right" cartridge slot together - that´s all! This mod is independent which TV system you have, it works also on NTSC as on PAL or SECAM. Regards, Jurgen
  11. I'm pleased to announce the release of the v.2.0 'alt' firmware for the Ultimate 1MB, Incognito, 1088XEL and SIDE/SIDE2. The update had been slated for release late in 2017, but the emergence of the 1088XEL and the requirement for custom U1MB firmware for the new motherboard heralded a prolonged period of firmware development and redesign for all supported devices. Since the 1088XEL's XEL-CF compact flash adapter can handle dual physical disks, I redesigned the U1MB PBI BIOS to accommodate primary and secondary devices, which in turn prompted significant alterations to the XEX loader. Many useful changes and augmentations were carried back to the 'standard' firmware builds (targeting the SIDE cartridge). Since releasing the 1088XEL U1MB firmware here a couple of weeks ago (which has been subject to a minor fix pertaining to DracOS compatibility since then), I realized that the SDX "soft drivers" (for SIDE, MYIDE, Colleen, etc, which hadn't been updated since 2014) could also benefit from some fixes and augmentations. Likewise the various APT tools (FDISK, ATRMNT, MOUNT, etc) on the 'toolkit' disk, many of which required amendments in order to work with the updated PBI BIOS. Then I remembered that the APT Toolkit manual and the APT API Programmer's documentation hadn't been updated in years either... It seemed imprudent to relase - say - the new SIDE/SIDE2 ROMs with old versions of the soft-drivers and outdated documentation, so the past couple of weeks have been spent on documentation and toolkit/driver updates. I finally started assembling the ROMs and ATRs a few days ago, and even this was a painstaking process. I closed my website down imagining that the site updates and media uploads would be completed within twenty-four hours... five days later, it was still closed. In any case, I completely underestimated the sheer volume of software, firmware and documentation, so I can only apologise to those who have recently been gently pestering me for the U1MB update via email. Many complain of poorly documented hardware and software products in the A8 community, so I hope the time I've spent on four fairly lengthy PDF manuals has not been wasted. Not everything is complete. The MYIDE SDX ROMs and drivers are not yet uploaded and many download sections have placeholders for the moment. But U1MB, Incognito, SIDE and 1088XEL owners may download the latest firmware and tools and consult freshly updated documentation: Download here: https://atari8.co.uk/firmware/ Installation instructions and readme files will be updated in due course. I reached the stage this evening where not uploading everything would delay release by another week or more. As usual, please use this thread to discuss any installation or usage issues. The updates to the SDX soft-drivers (SIDE.SYS, COLLEEN.SYS, etc) have not been subjected to testing by anyone but myself, so if any early adopters encounter problems, please let me know. Also released is the RAPIDISK driver (which allows faster HDD transfers at 20MHz) and Rapidus-specific BIOS plugins for U1MB (also on the 1088XEL). I hope to make some 'quick-start' videos and general guides over the coming days/weeks, but as usual it's all a question of available time.
  12. Decided to give this its own topic, since it doesn't really have anything to do with APT (previous posts were in the APT Hard Disk Preparation and Utilities thread). Can't start it with a download quite yet (although there'll be a version to test in a day or two), but I wanted to demonstrate the basic procedure for editing the flash ROMs so people can hit the ground running when I post a version of the software for testing. The video shows a PBI ROM update, followed by BASIC slot 2 being replaced by the Atari Assembler Editor. You'll notice the slot descriptions can be edited and flashed to ROM at any time. I then replace the High-Speed OS with the 1200XL OS. Flashing is somewhat slower than it would be when using 4KB sector flash ROMs (Altirra only emulates 64KB sector chips for Ultimate), and of course it's also possible to load all ROM images from the hard disk (in the video, they're loaded from the host device via SIO). Don't really want to spend too long on this, so hopefully it'll be done shortly. I need to add 4KB sector and Incognito support before I have something ready for testing.
