Subject: Problem booting FreeBSD from cboot FreeBSD from cdrom using grubdrom
using grub
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
