Ok. that fixed it.. ADLO is booting for me. For the list: I had to enable read and write in the shadow memory. I don't think you had to but I enabled the full range from 0c0000 to 0ffffff Adam: I added a macro that does a PCI config space write. Saves you from haveing to do all the calulations. Would you like a diff? It doesn't appear however that my video bios is getting called. I rememember seeing somewhere that I have to enable that? -- Richard A. Smith rsmith@bitworks.com

sweet.
For the list:

FWIW, need for doing this mentioned in the "HACKING" file.

sure. can you send it to me and list so that it gets archived. Though, as I said in the long term we probalby want to have this sort of stuff done in the LinuxBIOS rather than ADLO so that it can stay (err become :-) architecture independent.

I guess it is differnet for each case. Not sure what's it like in your particular case. What's is this gfx card? overall BOCHS BIOS should find the binary only vga bios in memory and try to initalize it. there may be some stuff in linuxbios to enable too. not sure. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers
ok, richard, how about a HOWTO? ron

Ah. RTFM then. Figures the one file I didn't read.

Asiliant (used to be C&T) 69000.
overall BOCHS BIOS should find the binary only vga bios in memory and try to initalize it.
Should there be any serial debug output? I don't see any thing that relates to video bios init.

nope. it is binary only vga bios. we have no control over it. it is why I don't like this solution. It is bit of black magic to get it to work. Did you try to boot with normal pc bios and then warm-boot into linuxbios/adlo? see if it helps. It might give you some tips.
there may be some stuff in linuxbios to enable too. not sure. Heres what came out the serial port:

umm are keyboard and mice connected? if no, I would connect them. umm what's at /dev/hda did you put there linuxbios or something? overall BOCHS BIOS will try to read MBR from /dev/hda and boot it. I would put there lilo and configure it for serial console. Then u should be able ot se if it reads MBR correctly and boot lilo. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers

The question is why is it blank. Does that serial debug patch route everything out the serial port. Or does is go to both the screen and the serial port? -- Richard A. Smith rsmith@bitworks.com
