      Part of my trouble is that when I enable VGA I don't get a boot log,
nothing happens, via serial or vga.  Config.lb for MB is below, and
config.lb for target follows.

Hi There,
Has anyone had any success with VMWare.  I have partially implemented the
PC87360 SIO chip which has give me serial and I can boot LinuxBIOS up to the
elf payload stage.  I'm trying to get the VMWare VGA to work at no avail.
Has anyone else has success with this.
I have added
default CONFIG_CONSOLE_VGA=1
default CONFIG_PCI_ROM_RUN=1
to the Optionslb file and adjusted the size of the ROM image by -32KB
(sizeof VGA BIOS for VMWare)
and also added
device pci f.0 on                         # VGA controller
            chip drivers/pci/onboard
                device pci f.0 on end
                register "rom_address" = "0xfff80000"
            end
        end
to the Config.lb http://config.lb/.
When I start VMWare with this image though it does nothing but sit there
with no VGA.  I have even enabled serial logging back on using
CONFIG_CONSOLE_SERIAL8250 but still continue to use CONFIG_PCI_ROM_RUN but
nothing then even gets written to the serial port.
When does the VGA BIOS rom get called, at what stage?
Regards,
Joe
