Just FYI on the Geodes in case anyone missed them...
The AMD Geode dev site has a few handy utilities and tools for debugging BIOS and driver settings.
Cyreg - Cyreg is a menu driven utility that displays memory, I/O and PCI configuration space data. The menus are defined in a text file that allows the user to easily modify each menu.
Loadreg - Loadreg is a command line utility that allows the user to read or modify any I/O, memory, or PCI configuration space location. It is ideally suited to modifying system registers via a batch file.
MCVAL - Mcval tests the state of the memory controller against known values, as well as lists all supported processor speeds and their associated memory controller register values.

Is there any Linux version?

I'm porting BIOS on a AMD opteron system with broadcom HT2000 and HT1000 chipset. I meet a problem when initilizing SATA device of HT1000. The SATA PHY status(0x40)always return a disable status(04), whatever I did with the PHY reset ( set 0x48 bit 0 and clear it ). Can anyone give me some advices? Thanks in advance!

They have Cyreg and loadreg for 2.2, 2.4 and 2.6 kernels
For 2.4 and 2.6 they have flashrom. The 2.4 version doesn't work very reliably on our reference design. There are a few other tools including a register tool used by flashrom available.
I'm curious if anyone who has used the xpressrom BIOS for the sc1100/sc1200 has tried setting up > 4MB of video memory. Or is there a pitch limitation? I don't know how the memory for VGA is aligned.
