Re: ADLO is GO

[Richard Smith]

      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?

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.

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

Asiliant (used to be C&T) 69000.

bios in memory and try

Should there be any serial debug output?  I don't see any thing that 
relates to video bios init.

not sure.
Heres what came out the serial port:

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.

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.

I got VSYNC but no text

Ok... Looks like it was actually working but I just didn't notice since 
the screen was blank.  But VSYNCS start happening so I know the chip is 
being initialized.

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?
