However, the documentation with the driver is incomplete and omits

controller bios setting.

Since this was a used machine and when I first booted it, Windows 2000
server login screen appeared, I accepted that the hardware is working
and all I did was delete the RAID5 configuration and reset to RAID1
before trying to load SCO. Three days later....

Steve,

What is the setting and I will add it to the TA.

John

The Perc4/Di was set in BIOS to I2O mode. Windows 2003 was happy
with that. The magic fix is to set the controller to "mass storage" mode.

After I made that change, I booted the OS6 CD and loaded all the drivers
I had downloaded: Perc from Dell, mega from SCO, and another version of
PERC from Dell. The installation then identified the card as mega,
and the installation finished without further problems.

I did not test your statement that OS6 will recognize the PERC 4 without
additional HBA drivers, I was just happy that OS6 was loading. I left for
the evening with the installation running, planning to return the next day
to complete the migration.

Interesting: Disk performance is much better in RAID1 with the mega driver then
I experienced when I set the controller to LSI (SCSI) mode. The MP2 patch
took 30 minutes to install in LSI mode and only 10-15 minutes in RAID mode.
