Introduction
~~~~~~~~~~~~
This is a small patch  which  will  fix  some  problems  occuring  on  some
machines  with  Blizzard  1230/III  and  SCSI-Kit.  This  'bug'  causes the
controller to perform very slowly. The patch  just  turns  off  the  caches
during scsi chip accesses. However, this made a change of the transfer rate
of under 80 KB/s to 2,6 MB/s of a friend's harddisk.

The patch can be made resident. If you don't use  BlizKick  you  *have*  to
REMOVE  the MAPROM Jumper on your board to avoid losing the RomTag at every
bootup!

NOTE: The blue stripes showing up in previous versions during booting  have
been removed.

Removal of the patch is possible both during reboot (by pressing  the  left
mouse button and not the right one), or using "1230ScsiFix OFF".

A BlizKick Module is also supplied.

I would really appreciate, if you could tell me, if the patch does its  job
on your machine.

Requirements
~~~~~~~~~~~~
1230ScsiStub needs Kick 2.04 or higher. Obviously also requires a  Blizzard
SCSI Controller.
