Hello,

Recently I wanted to resurrect and old AMD Bobcat (14h) for use with
kgdb over dconschat. The system booted a
FreeBSD-13.0-ALPHA2-amd64-20210122 without a problem. I noticed the BIOS
was ~9 years old, so I updated the to most recent version, which is ~5
years old. After the BIOS update, Any FreeBSD boot image I have tried as
far back as 11, no longer boots past the printed EFI framebuffer
information. NetBSD-9 and Kunubtu-20.10 all boot OK. I am not having
success with remote debugging via Firewire (I recall it used to be far
easier), even WITH_LOADER_FIREWIRE, I can still not attach a remote gdb
process. 

My other host which is connected to the E45M1 via Firewire reports when
the E45M1 is booting:
fwohci0: fwohci_intr_core: BUS reset
fwohci0: PhysicalUpperBound register is not implemented.  Physical
memory access is limited to the first 4GB

Any ideas on how I can restore FreeBSD on the hardware?

To good health,
Alastair
