| I was wondering why my PC doesnt read the CD Rom And CD Burner in MS Dos. I
have a multi boot system with 2 hard drives. Disk 0 has C: ( win98), E: (win
2000), and F: (Xp Pro). Disk 1 has D: ( data). my Cd Rom is G: and CDRW is
H: . Both CD's have no problem being read in any of the windows OS's. but in
MS Dos I get the message " Invalid Drive Specification" in Drives G: & H:.
Thanks
Mark

you need to load a cdrom driver for ms-dos
it'll be a .sys file
go www.bootdisk.com, grab a bootdisk for ms-dos
look at the config.sys and autoexec.bat files
config.sys will have a line that looks like
DEVICE=cdrom.sys /d:cdrom01
autoexec.bat will have a line that looks like
mscdex /d:cdrom01
(text from memory, so syntax is prob not quite right)
don't load up windows with a ms-dos cdrom driver loaded like this, at best
it'll kill the performance of your cdrom, at worse it'll screw windows up

| You need to load a CD-ROM device driver in Config.sys and also you need
to load MSCDEX.EXE in Autoexec.bat, and the command lines loading both
of them need proper [and, very importantly, matching] configuration
parameters].

| Mark,
You must have mscdex.exe in the root of c: (your harddrive) plus the
best thing to do is get an Atipi dos driver disc and run it.
This will write what is needed in the config.sys to recognize a CD Rom
when booting in dos.

| MSCDEX does not need to be in the root, it can be ANYWHERE, as long as
the line in Autoexec.bat that loads it refers properly to where it is
located, for example:
D:\Drivers\CDROM\MSCDEX.EXE {parameters}
Will work just fine if D:\Drivers\CDROM is where MSCDEX resides.
