For some reason BX_ELTORITO_BOOT was disabled when using ADLO. Does anyone know why? At this point I need qmeu + linuxbios_+ ADLO to be able to install windwos in a qemu image from the installation CD.
file: rombios.c Where can I find what are the current cmos settings? qemu + bochsbios is able to boot from the CD because bootseq receives 3 on the following piece of code. When using linuxBIOS, bootseq receives 2. // if BX_ELTORITO_BOOT is not defined, old behavior // check bit 5 in CMOS reg 0x2d. load either 0x00 or 0x80 into DL // in preparation for the intial INT 13h (0=floppy A:, 0x80=C:) // 0: system boot sequence, first drive C: then A: // 1: system boot sequence, first drive A: then C: // else BX_ELTORITO_BOOT is defined // CMOS regs 0x3D and 0x38 contain the boot sequence: // CMOS reg 0x3D & 0x0f : 1st boot device // CMOS reg 0x3D & 0xf0 : 2nd boot device // CMOS reg 0x38 & 0xf0 : 3rd boot device // boot device codes: // 0x00 : not defined // 0x01 : first floppy // 0x02 : first harddrive // 0x03 : first cdrom // else : boot failure #if BX_ELTORITO_BOOT bootseq=inb_cmos(0x3d); bootseq|=((inb_cmos(0x38) & 0xf0) << 4); Looks like I need to change some CMOS settings.
