Having had a fresh attack at my broken system tonight I discovered the
original PATA drive boots if I disable the SATA drives in BIOS. What
appears to be happening is that no matter the BIOS is told to boot
"IDE" (and doesn't have a SATA boot option) once the SATA drives have
enough formatting to look bootable to BIOS, the BIOS boots the ad4
SATA drive rather than the ad0 PIDE drive. :-(

I was trying to geom stripe ad4 and ad6, not ad4s1 and ad6s1. Made my
gstripe with ad4s1 and ad6s1 so that the boot MBR stays untouched.

System is now booting ad0 by starting at ad4 and hopping to ad6, then
to ad0.

Yes, you've discovered a "feature" of the 400SC (I have 3). If you
have PATA and SATA disks installed:

SATA disabled in BIOS -> PATA boots
SATA enabled in BIOS -> SATA boots, and stops if it can't (PATA never attempted)

The best work around is to install a boot loader on your SATA HD to
point to the PATA HD.
