Honestly dunno what it does at the low level, never looked closely at its internals, but it (MSCDEX, NWCDEX, SHSUCDX, etc.) basically is only used in conjunction with a CD-ROM driver, e.g. ATAPICDD.SYS, UIDE.SYS, etc. If you don't need (or want) CD access, you can ignore it. > c) Is it necessary to include "shsucdx.exe"? Here (when using RDISK as RAM driver)? No, not for this task. All you really (!) need are KERNEL.SYS, COMMAND.COM, XMGR.SYS, RDISK.COM. Of course, feel free to add more. :-) P.S. I think all current FreeDOS XMSv3 drivers require 386+. For instance, FDXMS286 is only XMSv2 (64 MB limit). Jack's RDISK is limited to 2 GB, I think.

Re: [Freedos-user] tdsk.exe to create 40MB of disk space
Hi, Thanks for your reply. I am creating ramdisk with Letter drive "E:" using rdisk. I've included Rdisk command in the "Autoexec.bat" file. Also, I've included one more command "shsucdx.exe". This is shown below. LH RDISK.COM /S 40 /:E shsucdx.exe /D: CDRCACH$ I was able to create the directory. In addition to that, it is creating "C" drive but that was not formatted. I want to know the following details: a) What is the use of shsucdx.exe b) Whether shsucdx.exe creates any drive. c) Is it necessary to include "shsucdx.exe"? Thanks, S.

What you really need for large RAM is XMSv3 ( = more than 64 MB). My only complaint against SHSURDRV is that there are two separate versions (XMSv2, XMSv3) instead of both integrated.

Is there any way to accomplish this or is there any other tool? Any help is appreciated. In what situation do you want to create space? If working with non-writeable or non-detected storage, the most convenient way is using a RamDisk, which marks a memory area as a storage disc until you unload the driver or reboot your system (because memory loses contents on reboot). Your suggested TDSK works, but also SRDISK, XMSDSK or SHSURDRV, make sure to load an XMS driver like HIMEM or XMGR first. * For conventional memory as ramdisk, I think only TDSK can do it. If anyone knows any other program, I'd be interested.
