Hi,
I'm trying to make an iso image that will boot FreeBSD using GRUB boot
loader.
Grub will boot /boot/loader and the loader will boot /boot/kernel. It
goes well on my disk, but when I try to make a livecd, it fails. I spend
some time figuring out that /boot/loader does not probe cd it self, it
depends on boot2 to tell him which cd to boot from. So I did some hack
on /boot/loader. Bellow is the diff:
*** sys/boot/i386/loader/main.c.bak Sun Dec 11 19:32:29 2005
--- sys/boot/i386/loader/main.c Sun Dec 11 22:04:29 2005
***************
*** 228,235 ****
if ((new_currdev.d_type == biosdisk.dv_type) &&
((new_currdev.d_kind.biosdisk.unit = bd_bios2unit(biosdev)) ==
-1)) {
printf("Can't work out which disk we are booting from.\n"
! "Guessed BIOS device 0x%x not found by probes, defaulting
to disk0:\n", biosdev);
! new_currdev.d_kind.biosdisk.unit = 0;
}
env_setenv("currdev", EV_VOLATILE, i386_fmtdev(&new_currdev),
i386_setcurrdev, env_nounset);
--- 228,238 ----
if ((new_currdev.d_type == biosdisk.dv_type) &&
((new_currdev.d_kind.biosdisk.unit = bd_bios2unit(biosdev)) ==
-1)) {
printf("Can't work out which disk we are booting from.\n"
! "Guessed BIOS device 0x%x not found by probes, defaulting
to cd0(%d):\n", biosdev, biosdev);
! bc_add(biosdev);
! new_currdev.d_type = bioscd.dv_type;
! new_currdev.d_dev = &bioscd;
! new_currdev.d_kind.bioscd.unit = bc_bios2unit(biosdev);
}
env_setenv("currdev", EV_VOLATILE, i386_fmtdev(&new_currdev),
i386_setcurrdev, env_nounset);
Then the kernel starts, but when the kernel try to mount the root fs, it
stops. I have the follow line in my /etc/fstab
/dev/acd0c / cd9660 ro 0 0
I am stranded. Can anyone help? I'm using FreeBSD 5.4
thanks
Tony
