Which device were the registers in? //Peter

I was surprised how easy it was to brick my board. These ideas might be useful to somebody:

Before you start messing with PCI& I/O values that might keep their state:

- have a lspci -vvvxxx from the factory BIOS - record as much of the boot process from the factory BIOS as possible

I wanted to collect the bit masks from my factory BIOS, so I modified the filter to return 0x0 and then 0xffffffff for the PCI registers. That way I could see which bits were being changed. After some of the registers were changed, I couldn't boot the board with Coreboot or the factory BIOS. I used SerialICE to set the PCI values to what they were in a saved run of the factory BIOS, and it booted again.

Wow that is interesting. Even after you disconnected power (ATX connector) and cmos battery it would still keeps those values? -- Thanks, Joseph Smith Set-Top-Linux www.settoplinux.org

Wow that is interesting. Even after you disconnected power (ATX connector) and cmos battery it would still keeps those values? Since I could recover with SerialICE I didn't try it. I was surprised that the factory BIOS wouldn't set the values correctly, though.
