much thanks Tom H.
yes , and I notice that the config of openSUSE in grub.cfg is
menuentry "Desktop -- openSUSE 11.3 - 2.6.34.7-0.5 (on /dev/sda12)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos12)'
search --no-floppy --fs-uuid --set bff01541-50d4-4428-9c65-4d0cdb25cfb8
linux /boot/vmlinuz-2.6.34.7-0.5-desktop
root=/dev/disk/by-id/ata-WDC_WD10EADS-65M2B0_WD-WMAV51524747-part12
resume= /dev/disk/by-id/ata-WDC_WD10EADS-65M2B0_WD-WMAV51524747-part8
splash=silent quiet showopts
initrd /boot/initrd-2.6.34.7-0.5-desktop
}
in the "initrd" line, it avoid using the (hd0,msdosx) to refer to the
position of "initrd". So it works .
and why does the auto-probe fail ?
Thx~~
