Load 5.0.7 On A Dell Pe6350/550

I'am new to this and want to learn more.
I would like to load SCO 5.0.7 on a dell poweredge 6350 with quad Xeon processors 3 drives with 2 meg mem, SCSI 7890, 7860 .
the problem comes when ths software does its system check, confus
it gets to a point, and shows F Bladinit , then stops and shuts down.

if have tried different defbootstr still no luck

The problem is that SCO cannot find the harddrive, or that it cannot find the correct controller. The part numbers you have shown suggest that the system has an Adaptec controller. If this controller does not use the alad driver, then you may have to download a driver from Adaptec's web site, and then use btld to load the driver, and add Sdsk=xxx(0,0,0,0) to the bootstr, where xxx is the name of the driver, and you might also have to change the 0,0,0,0 to something else if the driver uses a different host adapter bus, or different lun number for the boot disk.
