[LinuxBIOS] PIRQ REF DES AMD LXUVCRDK - coreboot

20 Jun 2007

      Hello to all,
I'm porting a linuxbios v2 version for a board ref des LXUVCRDK (
http://www.amd.com/geodelxuvcrdk) based on norwich board. I've already got
to boot linux from HD, but it seems to halt in some point (see log below
captured from serial). Although,  I'm using VSA (lx_vsa.36k.bin) and I got
no output from video VGA.
          I'd like some help for setting up the PIRQ table and for VGA
setup.
PS: The schematics for this board are publicly available from AMD Embedded
Developer Web Site.
Thanks,
