Checkout the MS-DOS Starter Pack at Phil's Computer Lab:

Something like this...

config.sys

1device=himem.sys /testmem:off
2dos=high,umb
3devicehigh=emm386.exe RAM
4devicehigh=cdrom.sys /d:CD001

autoexec.bat

1lh mscdex.exe /d:CD001

Create one from Win98.... (format a /s)
Then add the basic stuff like format.exe, attrib.exe and so on from the windows installation it self.
You need to edit autoexec.bat and config.sys manually.

It will give you the exact same options as MS-Dos 6.22, yet the procedure is the exact same as Win98.
Else you can open autoexec.bat and config.sys from the Win98 bootdisk, then copy the lines,
then change disk and open the autoexec.bat or config.sys (without closing edit) and paste the lines.
Finally copy whatever files/drivers/tsr's you need from one disk to the other.

That is how I make CD-Rom support on my Dos6.22 boot disks.

Create a bootable disk with format /s. Every time you run into a situation and don't have the util you need, copy it to your disk. What I need isn't what you need, and vice versa.

For me, it's CD stuff, SCSI drivers for the couple chipsets I use, himem sys format edit attrib move fdisk deltree, pkunzip.
