Hi! I have problem with MEMDISK, because when I load modules in NW Client32 using NIOS.EXE commands, computer is restarted :-( Not everytime, but manytimes. The problem is with MSDOS 5.0, 6.22 and FreeDOS too. But when I create in DOS another RAMDISK and copy all data from MEMDISK to new RAMDISK and change settings and PATH to new ramdisk, all work fine. Directly from floppy or from HD all work fine too. But two ramdisk is not good situation. Does anybody have some experiences, how to debug this problem? I hope, i will be certainly some little error in asm. poli
Hi Petr, It sounds like you might be using the standard Microsoft (tm) ramdisk.sys's with NetWare Client 32 to logon from DOS? I would suggest trying Franck Uberto's excellent XMSDSK.EXE instead and seeing if that helps you with your problem: http://www.simtel.net/pub/pd/4825.html (I would suggest downloading from here) http://www.geocities.com/politalk/rmdrv/fu_rd19i.htm (this provides a useful file list) From what you have described it sounds like your problem may be with the DOS NW client over-writing something else in memory. I would look into this by booting without loading the NW client and typing the DOS command "mem/d | more" to see where the address of the ramdisk is going. Then check your net.cfg etc to see if you are loading your VLM's etc into memory areas already used by the ramdisk or memdisk etc. Tip: you can also visually see what is located where in "low" DOS memory by using ramspy: http://www.programmersheaven.com/download/15858/download.aspx Regards Richard Petr Olivka <petr.olivka at vsb.cz> wrote: Hi!

Then you have full visibility. If it *doesn't* reproduce there, then you at least know it's a hardware-specific thing. Then I've had some limited success tracing through the program under Turbo Debugger (a DOS debugger from Borland), since you can get DOS up and running at least. -hpa
