[SeaBIOS] Searching for an MS-DOS CD driver

Agree.

dos is even older though, it used to *not* ship with a standard ide
cdrom driver. mscdex alone isn't enougth to make it fly, it is some kind
if "high level" driver (basically handles iso9660 filesystem I think)
which needs another one for the actual hardware access.

Best bet is to grab the one shipped with freedos these days I guess.

HTH,
