I take it you read http://aplawrence.com/cgi-bin/ta.pl?arg=104924
because you disable IC Initialization. Here is the description for
Trap 0x6: "Invalid op code. Can be caused by any illegal instruction,
cacheing, bad hw, bad instruction from memory or bad memory itself." Lots
of things could be going wrong (like bad memory, bad SCSI termination).
Did you read http://aplawrence.com/cgi-bin/ta.pl?arg=105532.

Because you didn't give any other indication on how you installed
your system, I'd perform my failsafe installation technique for large
hard disks. Create a small 1GB or smaller partition using some other
product. I happen to use a RH install disk and get to the point where
you are allowed to partition the HD and create one using the low-level
partition utility (not disk druid). Abort the RH install and install
4.2 on the small partition. Partition the rest of the disk after 
the installation succeeds using SCO's fdisk.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
