Type "MEM" to display MEMLO, among other things.
It would be nice to have something like Altirra or Turbo Basic work with Side2 and no additional RAM, since I could see wanting to pop the Side2 cart into various machines, some with and some without extended RAM capabilities. Although all of my Atari's are XL or XE with 64k, which is obviously a bit better than a stock 800. So once again I see the reference to changing CONFIG.SYS, is there a good tutorial on just doing that? I browsed through the SDX manual, and although I see it talked about, it isn't extremely detailed which is what I need. Also how would I look at the CONFIG.SYS that presently exists, because it certainly isn't in any of the APT partitions on my CF card, so I'm assuming its in CAR???
Download the SDX Imaging Tool from this page:http://sdx.atari8.in...?show=en_addons
The program is fairly simple to use: you load the SDX ROM you want to modify, change it, save it, and flash it back to the target device. You'll need to start with a stock SDX ROM image for SIDE2, or the image on my website, or extract the binary from the actual flash ROM on your device (for which you can use UFLASH). Play with the stock ROMs first to get a feel for the editor, then we can walk through flashing, etc, if necessary.
You can edit CONFIG.SYS right in the imaging tool, fortunately.
The whole matter of HDD operation inside 64KB has been discussed a lot and various solutions found. MyIDE favours a soft-loaded customised OS to make the operating system "see" the cartridge-based hard disk, although this custom OS is better off in ROM, which in turn requires removal of the masked OS ROM chip, some kind of EPROM, or indeed Ultimate 1MB itself. And once you have Ultimate 1MB and SIDE, the solution presents itself via different means anyway.
With SIDE, we chose to target operation at SDX, since SDX is able to load the drivers from the cartridge at boot time (something no disk-based DOS is capable of doing). The HDD isn't bootable, but even with 128KB, it's a very usable system.
The ideal portable solution is a plug-in, proper PBI host adapter such as IDE Plus.
EDIT: I'm thinking that the existing CONFIG.SYS is not changeable without re-flashing the SIDE2. So would that would mean creating a new CONFIG.SYS and placing it into the first APT partition Drive C: (D3), which I assume if it existed would be used instead of the built-in one?
Not exactly. For the reasons outlined above, the CONFIG.SYS in the SDX ROM (i.e. the default CONFIG.SYS) needs to reference the SIDE driver (SIDE.SYS), so in this case - peculiarly - it's the CONFIG.SYS in ROM which needs to be changed. Having said that, there are ways to merge CONFIG.SYS files to partially overcome this which I'm not intimately familiar with, but which are nevertheless explained in the SDX manual.
