Bootable USB with CD ROM Support

Ho do I make a Bootable USB with CD ROM Support?


I already have it booting to DOS but there is no CD ROM support.

Presuming internal CD-ROM support you can just add a driver to it and load it in the normal way.

See https://sourceforge.net/projects/cdromdosdrv/

If your intention is to end up with a DOS operating system including CD support on a bootable USB Flash Drive, I would suggest you look at Rufus to create the bootable USB drive from a FreeDOS ISO.
You can read about FreeDOS here.

This is all a bit retro, isn't it?!

I think you need to install the driver and use autoexec.bat and config.sys to load it.


Something like this...:
http://manmrk.net/tutorials/DOS/cdrom.htm

that

the is a line in Autoexec that had this blow and it effects the cd drive
MSCDEX.EXE /D:MSCD0001


in the config.sys the must be an entry
DEVICE=C:\MTMCDAI.SYS /D:MSCD0001

Think that MTMCDAI.SYS file was manufacturer dependent?

Depending on age, you may not be able to boot from CD rom. Dos needed drivers to get the cd to work. Some CD drives connected the fat cable to the sound card (as well as the thin cable), rather than ide port - I think, but depends on age, and there was another device driver in config.sys for the sound board that controlled the CD interface

Some were but it was far easier to use a generic one, for IDE/PATA drives to use oakcdrom.sys which was generic and worked on 99.9% of configgurations. Gcdrom.sys for SATA DVD drives did the same job.

The sound card configuration required were rarely needed unless you had something relatively obscure and the defaults tended to work fine.

The audio cable of which you speak was only primarily used for audio CDs and for a while it was the only way of playing them, similar to "line in" if you like. When digital extraction came along it didn't use the audio cable as that was an analogue output. The data came down the IDE/SATA cable and across the main board digitally.

that

To be honest stretching my mind here:D. I was never involved with DVD drives and dos though. I did not spend a long time with 98 either, but moved to nt4

Do vaguely remember some of the fat data cable plugging into the sound card, rather then ide port, until it no longer did

Think it depends on how old the machine is, and if is new enough to boot off an ide CD drive. Think the really old done could only see around 500Mb on the disk, and some older not even that
