All the drivers I used were included with the Slackware distribution for Linux
2.0.0 (from Walnut Creek or Infomagic) All I had to do was to select the
boot image aha2x4x.s from the installation cdrom and write it with rawrite onto
the "boot floppy". The root floppy I used was the text.gz, which I
uncompresssed and rawrote to the "root floppy". It recognized the adaptec card
and the two devices I had daysi-chained to it (a hard drive and a tape drive)
The file you found contains the drivers for this card. However, I suspect you
probably want to install Linux onto your SCSI disk so you need this to be
recognized upon bootup. I think that you DO HAVE to use a bootimage that
contains the aha2x4x driver (there might be other ways Im not aware of)
Before you spend too much time on this (as I did) I sugesst you install from a
Slackware (or Red-Hat or whatever) distribution that contains a bootable image
for this card
