I am trying to use FreeDOS on a weird old electronic message board, which is driven by a headless 80286 motherboard. My only access is via a floppy drive, and I do not have the ability to use a normal VGA video card. So instead I create a boot disk which writes test results to a log file.
I need to create a RAMdisk using the spare memory above 640k, but a large chunk of XMS is being consumed for some unknown purpose. The standard FreeDOS kernel in FreeDOS 1.0 / fdbasecd.iso doesn't work on this 286 and hangs during boot. So instead I am using the updated kernel from: http://www.coli.uni-saarland.de/~eric/stuff/soft/by-others/ke2007sep07.zip As mentioned here: http://bugzilla.freedos.org/cgi-bin/bugzilla/show_bug.cgi?id=1755 --------------------------------------------- FDCONFIG.SYS looks like this: DEVICE=A:FDXMS286.SYS DOS=LOW,NOUMB --------------------------------------------- AUTOEXEC.BAT looks like this: mem /c >> log.txt --------------------------------------------- Log file results: Modules using memory below 1 MB: Name Total Conventional Upper Memory -------- ---------------- ---------------- ---------------- SYSTEM 63,360 (62K) 63,360 (62K) 0 (0K) FDXMS286 1,664 (2K) 1,664 (2K) 0 (0K) COMMAND 3,296 (3K) 3,296 (3K) 0 (0K) Free 586,960 (573K) 586,960 (573K) 0 (0K) Memory Type Total Used Free ---------------- -------- -------- -------- Conventional 640K 67K 573K Upper 0K 0K 0K Reserved 384K 384K 0K Extended (XMS) 2,549K 1,689K 860K ---------------- -------- -------- -------- Total memory 3,573K 2,140K 1,433K Total under 1 MB 640K 67K 573K Largest executable program size 573K (586,832 bytes) --------------------------------------------- This log file is mystifying... so there's a total of 2.5 meg XMS available, but something is consuming 1.6 meg of that? I need as much free XMS as possible for the RAM disk. How do I find out what is using that XMS, and how do I free it all up? -Dale ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
