1047 221 occurs when no SCSI device attached. Your re-install must of
cleared the error condition. FD BIOS, set HD to ID0, IBM BIOS, set HD to
ID6. IBM used the ANSI standard, ID7 for SCSI controller, then downward.
Most everyone else used ID7 for the SCSI controller, but ID0 and up.
Did you use XGAOPT to patch theP70 refdisk?
http://ps-2.kev009.com/ohlandl/video/xgaopt.exe
Installs the updated (as of '92) SC.EXE, XGA/2, and SCSI, SCSI
w/cache ADFs, plus updated *.dgs. For 5565, 5657, 70486, 7080, 7677, 90,
95, P70, P75

Whenever I have used a Patriot, it reports itself as an IBM SCSI-2
adapter. But I have never tried updating the MCS-600 with an IBM BIOS.
It is possible that the MCS-600 reports itself differently. The TMC-1800
was known to have issues that required some software fixes that the
later TMC-18C50 corrected.
> Since I am not fully as used to have IBM does the plug & play / auto
config thing with ADF files I simply do not understand how the machine
detects the board as a FD board rather than a IBM board. What would be
the difference between a MCS-700 and a IBM SCSI and how can the machine
detect it?
Again, I am used to the MCS-700/TMC-18C50/IBM BIOS. Every time I have
used a Patriot, it shows up as an IBM SCSI-2. I can't remember if it
shows up under set and view SCSI devices, it should.

Very possible.
> Regarding the BIOS how does the IBM announce itself when starting?
The FD BIOS showed a banner and searched for disks. With an IBM bios it
just takes quite long time to start.
The IBM adapter will NOT announce itself during boot. Not sure about the
long time. SCSI HD set to ID6?
The FD BIOS will show a banner, and it should look for a HD at ID0 (or
ID1). If it cannot findt a HD at ID0 or ID1, then it does not boot.
Did you patch your refdisk with XGAOPT to get the '92 version of Set
Configuration (SC.EXE)?
IBM BIOS card should be ID7 (default) and the SCSI HD should be ID6.
What SCSI HD are you using?
