I am currently trying to install a new Seagate ST5108A 1GB hard disk.
It came with no manuals or software.
My computer (Research Machine 486 DX2) will auto-detect the new drive
correctly, but when I go to DOS and try to format the new disk it is
not found.  Drive c: is just reported as an invalid specification.

I have just be told to set LBVA (large block address) to enabled in
the bios, but there is no such setting.  It was suggested that I get a
new bios driver from the hard disk supplier.

This is now getting beyond me.  It would seem that my machine can't
read large drives (opposite to what I was originally told), so can
someone enlighten me as to what to do next and if it is possible to
get the required drivers off the net ?

Thanks for any help.
