[coreboot] Now that I swapped in my other P2B-LS, I finally found out a few things

[Keith Hui]

I have two P2B-LS mainboards. I have been doing development on a newer
rev 1.04 "Dot" board while my desktop runs a rev 1.03 board heavily
modified by myself [1]. It's my "Trophy" at my high times in modding
things.

Tonight I swapped my two P2B-LS boards so I can try coreboot on Trophy.

I know 1.04. has Winbond 83977EF for superio. Found out 1.03 has W83977TF.

The reason why SCSI isn't enabled properly is because my 1.04.
actually has broken Ultra2 SCSI hardware. I have to put my drives on
the single-ended ultra-wide port for them to be detected at all. And I
don't think it's a termination problem. Is it possible that my
previous attempts at getting the SCSI bios to load fry the hardware?

Now I need to bring in serialice to find out how the onboard
termination is controlled.

Once I figured out how to control this termination, where should I put
code to control this? A driver like Sil3114 or add to the board level
romstage?

I should update the wiki with my findings.
