  1. Hi, Following on from http://atariage.com/forums/topic/287691-ramdisk-driver-for-dos-25-and-sys-check-2-512k-ram/ I have tried out various configurations of MyDos and the RamDisk drivers together with a Sys-Check 2 card, and have managed to get it to work as a 512K Ramdisk. I ended up using MyDos 4.53/4, as this is supported by dir2atr (MyDos 4.55 isn't supported by dir2atr). I used the MYRD2 ramdisk driver, which is part of MYRD.ARC (written by Lee Barnes). I've attached a working ATR that should be good for anyone to use with a Sys-Check 2 card (I followed the instructions in the Ramdisk readme, and wrote the Dos files back to disk after booting with the Ramdisk driver). The files on the disk are: DOS.SYS, DUP.SYS - MyDos versions MD.ARC - Compressed Disk Communicator image of MyDos MYRD.ARC - sources and ramdisk drivers DISKCOMM3.EXE - disk communicator 3 by Bob Puff MYRD2.AR0 - the Ramdisk driver that works with SysCheck 2 for 512K Ramdisk UNARC.COM - super-unarc by Bob Puff Thanks to all that helped, I got all the files from http://mathyvannisselroy.nl/mydos.htm - I've just combined them into a single ATR for ease of use. Hope this helps. MyDos4.534.ramdisk.syscheck2.atr
  2. Hi I have created a 16MB ATR for MyDos (4.534), and it boots fine (see attachment), but I can't figure out how to get large files out of the disk image. I can't copy them to an enhanced density disk (physical or ATR), as MyDos has its own 1040 sector file format, I think the same goes for DD disks too. Even if I could copy them to a physical disk, or standard sized ATR, I'll still be creating files larger than a DD disk, so this path probably won't work anyway. There don't seem to be any Linux tools that will extract files from an arbitrary large MyDos ATR (and I'm not sure there are any tools that will work with sub-directories either). I was hoping to be able to use the Linux atari800 emulator (the emulator will read the big ATR perfectly), and then copy the files to a folder accessible on H1:, but writing to H1: doesn't seem to work with MyDos. So I can make very large files on MyDos (>90K), but can't copy them onto a PC. Is there an obvious work-around? I am using sio2bsd to emulate drives with ATRs, and it seems to work fine, though it seems to have some issues with high-speed/DD loaders such as Alpha-Load, and possibly SpartaDos, which probably complicates things. Also, the atari800 emulator is version 3.1.0, if that helps. Most of the time I use atrcopy for extracting files from ATR images, but it doesn't handle big ATR files. Any help would be appreciated! big_mydos_disk.zip
