As it's a standard cpu card you use I can't really help you with the update of the scsi.device, but if anyone else has this problem here is a thought.
Download BlizKick and install it as descriped in the docs. In the docs you will also find something called "how to make a single boot OS3.5/OS3.9 system". In here it is descriped how to cut the romupdate into pieces, you then can type in after the BlizKick command to get all the things in rom update executed, and not having the computer reset once more. It already did that when copying Kickstart to fastram.

You might try downloading this, but you need to be able to copy your Kickstart to fast memory. Try dusting off your manual and see what it says.
As goes for the BAD CODE alert. Have you tried checking for virus recently? I have had the same experience once, and after checking my SYS: with VirusExecutor there were found 22 viruses. After I removed the virus all was fine. I found the Happy New Year and the Ebola virus on my drive....
Send me an mail if you need to know more :-)
