Hi,
I had an A3001 @ 25 MHz in the past and I managed to re-write the IDE driver of the board.
Mine had ATAPI CD-ROM support :-).
I also remember that the original driver only supports CHS addressing (540 MB max) and that the A3001 was not compatible with the LS-120 drive.
I have to dig into my CD-ROMs to see if I have an archive somewhere...
Regards,
Frederic
