[LinuxBIOS] LinuxBIOS - Booting Windows XP

[Augusto Pedroza]

I have created two diff's, the first one is for linuxBIOSv2 (xpboot.diff)
the second is for LinuxBIOSv3, it adds ADLO to v3.
details:

Feel free to test it and give some feedback!!

We hope Vista comes soon.

I can get it to find my CD-ROM drive, but it fails with code: 0003.

According to http://bochs.sourceforge.net/doc/docbook/user/bios-tips.html
that means:

For this error, the cdrom support has not been compiled in Bochs, or Bochs
could not open the file or device. This is what you get if Bochs is not able
to read the cd.

Could you give me pointers as to what CD support I should add/enable in
ADLO?

Thanks,
Myles

Here is the output of the boot (First it tries the CD, then the HDD):

Hi Myles,
  in the xpboot.diff the following alterations should be made:
In the file:
 util/ADLO/loader.s

comment out or remove the lines 177 until 180:
;mov  al, #0x3d ;; cmos_reg
;out  0x70, al
;mov  al, #0x02 ;; val (hdd)
;out  0x71, al

In the file:
util/ADLO/bochs/bios/rombios.c

uncomment  line 147:
 #define BX_ELTORITO_BOOT 1

Have you done these alterations already?
Also try booting your windows installation CD with qemu default's BIOS and
let me know the result please.

Thanks,
  Augusto Pedroza

I've tried your fixes.  I'm trying to boot on a real machine, so I can't use
qemu's BIOS.  I'll keep trying.
