RE: grub in mac

[Peter Cheung]

Thanks i changed the device.map but still getting the same error :-(

>cat device.map

(hd0) /dev/disk2

>$base/sbin/grub-bios-setup --no-rs-codes -m device.map -c ../../`pwd`/temp/boot/grub/core.img -b ../../toolchain/lib/grub/i386-pc/boot.img $deviceName

/toolchain/sbin/grub-bios-setup: error: guessing the root device failed, because of `disk `hostdisk//dev/rdisk1' not found'.
