[syslinux] MEMDISK reset computer with NW Client32

:-) I am using XMSDSK and work fine. And with RAMDRIVE.SYS all work fine 
too. Problem is only with MEMDISK, if client32 is loaded from drive 
emulated by MEMDISK.

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.

And now I do not exactly understand to you. I do not have VLM modules, I 
have  client32 with NIOS.EXE, because we have clean IP environment. 
And MEMDISK is not visible, because is loaded before MSDOS in memory under 
videoram, some kilobytes under A000:0 and mem can't display it.
