In Option.lb,
default HT_CHAIN_UNITID_BASE=0x06 default HT_CHAIN_END_UNITID_BASE=0x01 default SB_HT_CHAIN_ON_BUS0=2 Just as Mr. Tom Sylla's setting.
I had tried the device numbers of 3, a and b respectively, it still didn't work. The attached is the boot log with the device number of b. There is totally no boot log if with the device number of a.
Best Regards

did you try chip drivers/pci/onboard device pci a.0 on end register "rom_address" = "0xfff80000" #512k image end
or chip drivers/pci/onboard device pci b.0 on end register "rom_address" = "0xfff80000" #512k image end
etc...
let me know your HT_CHAIN_END_UNITID_BASE and HT_CHAIN_UNITID_BASE in Option.lb. also boot log in serial port.
