Could you get the required information from an USB? It seems that SATA support for DOS is quite rare nowadays, but there seems to be a little more going on with USBs.
What would you like to do with the computer? There could be some alternative solutions for your problem, but I can't tell since I don't know what you want to do.

As a sidenote, I think I was able to play Wing Commander 1 on AMD1200 Duron and Windows XP around 2006, without actually installing DOS on HDD. It had something to do with DOS 6.22 bootdisk, CD-ROM and creative use of RAMDRIVE.SYS.
