		For that card, no drivers are needed for the hard drives. The on-board ROM is an Int13 wedge.
Regarding using any other devices like a ZIP drive, CD or a floptical, not sure if those need drivers. ZIP definitely needed a DOS driver. The CD did as well (In both config.sys and autoexec) but the ROM may have CDROM extensions already to enable booting from CD. Never tried it with that card though.

Do you have (and can you post) the MS-DOS drivers for that card?  I
also run one in my floppy imager machine, which dual-boots btw. MS-DOS
and some later Linux.  Having SCSI for at least one of the OSes would
be nice.

I could also switch the other partition over to FreeBSD, as Warner L suggested.
