I'm still not very good at DOS
I set up a fresh simple 6.22 system and I can't get my CD-rom to work as E: drive.
I have 2 HD's in this system C:, D: SO I want the CD-rom to be E
Here is what I have
Autoexec
C:\DOS\MSCDEX.EXE /E:CD-ROM /L:E
I get an error here on boot.
Config
DEVICE=C:\OAKCDROM.SYS /E:CD-ROM
This seems to work, but am unsure
Oakcdrom.sys is in the dos directory, as is mscdex.
I know it is just one letter that is off but I can't figure which one.
Could one of you guru's out there reply with a quick note?
Thanks 😀

The /L:E part is right, but you need to pass /D: to oakcdrom and mscdex (not /E:) to set the driver name.

DEVICE=C:\OAKCDROM.SYS /D:CD-ROM
C:\DOS\MSCDEX.EXE /D:CD-ROM

The "/D:" parameter for OAKCDROM.SYS and MSCDEX.EXE specifies the character device name, not a drive letter.
No need to specify the drive letter - A: and B: are reserved for FDDs, next are HDD partitions (in your case C: and D:), and finally drives controlled by drivers loaded in CONFIG.SYS and AUTOEXEC.BAT, eg. CD-ROM.

Nie tylko, jak widzicie, w tym trudność, że nie zdołacie wejść na moją górę, lecz i w tym, że ja do was cały zejść nie mogę, gdyż schodząc, gubię po drodze to, co miałem donieść.

As others mentioned, the /D parameter should be used for the specified driver name. In your case, the /L:E parameter isn't even necessary since it will be always assigned as drive E when loaded correctly.

As I have learned recently, the name you specify in “/D:” might not be accessible for normal files (in this case, a file named “CD-ROM” cannot be opened while the driver is loaded) so a name like MSCD0001 or something might be better there to reduce the chance of name clashes.
