[comp.sys.ibm.pc.hardware] AMI BIOS & Hard Drives

coxs@pawl.rpi.edu (Sean Cox) (11/13/90)

       Does anyone know if it's possible to "program" the AMI BIOS to
  accept a hard drive other than the 40-odd disks they have preset? I
  have a Seagate drive that isn't listed in the docs I have, and no 
  comparable drive (sectors & heads) is listed. BTW, the BIOS I have is
  for a newly purchased '386.
       Thanks in advance.

                                            -Sean

The AMI Bios I got with my 386 motherboard (purchased 6 months ago)
has a drive type 47 for user defined drives.  After selecting type 47
you are prompted for heads, cylinders, rwc, lz, etc.  If this isn't
present on your system, you may want to investigate a BIOS upgrade.
ALternatively, you can use Disk Manager from OnTrack Systems.

	Usually AMI Bios's have a drive type 47 which is user definable. Simply
select this type and you should be able to now enter the drive parameters in
the appropriate places.

The solution is (it is for my 4-1990 dated version of the AMI BIOS) : use the
user definable harddisk no 41 (or such, I am not sure; it is listed somewhere)
to set yer harddisk parameters.

Hope this helps you out,

    Option 47 should be the user definable setting.

Yes.  We've had to do it with a few uncooperative Epson 286's.
You need a prom reader/burner, some blank prom, and you need to
be able to unassemble the prom, once you've read it.

It's easier just to use a utility like Speed Stor, HardPrep or Disk Manager
which let you enter a non-standard drive type.  HardPrep is best for
this, but follow the instructions carefully for formatting and partitioning
the drive.

Disclaimer:  You do it, you screw up, you take the heat.
