Can someone point me to a public domain or shareware version of software to set up a RAM disk in the extended memory portion of RAM on an AT machine? (The only one I could find in the SIMTEL-20 archives is LESDISK (msdos.sysutl), but its poorly documented, and I can't get it to work on my machine.)

Is there anything wrong with the VDISK.SYS (or RAMDISK.SYS on some clones) that comes with DOS? If you make use of the /E option, it will very happily make use of extended memory. -- Simcha Lerner Kurzweil Applied Intelligence PLEASE NOTE ADDRESS: NO RETURN MAIL VIA bbn PLEASE UUCP address: kurz-ai!simcha@talcott.harvard.edu or: ...{uunet,rutgers,ames}!harvard!talcott!kurz-ai!simcha

Most recent versions of MSDOS include VDISK.SYS. It will create a
ramdisk in extended memory instead of normal memory if you put a
/E on the end of the command.
Example:
DEVICE=VDISK.SYS 512 /E
will create a 512k ramdisk in extended memory.
Check your DOS manual for details.

Small correction: PC-DOS contains VDISK, some versions of MS-DOS from various HW manufacturers (such as Compaq) also ship a VDISK. However, MS-DOS contains a program called RAMDrive.sys that performs the same function. Perhaps a better use of extended memory for many users is the disk cacher SMARTDRV.SYS that ships with MS-DOS. consult your local DOS reference for details.
