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.
