Grub2 sata ahci dvdrom and hard disks ASUS P5Q-LE Mobo

Hello all

I downloaded grub1.7beta4 and compiled the source. I made a grub2 bootable cdrom using grub-mkrescue.

When I boot from the cdrom with all the drives in AHCI mode. Grub2 cannot read the grub.cfg file on the cdrom. The drive is an ASUS sata dvdrom.

The ls command shows me my hard disks (hdo) (hd1)(hd2). But grub2 does not show the partitions inside the drives - giving an error like "can't find C/H/S)".

When I put the SATA controller in IDE mode mode. I get to the grub.cfg menu but when I try to boot an entry it says "no drive".

I have included modules "ata scsi serial boot" in the grub-mkrescue command.

Any ideas someone.

forgive my ignorance....what does AHCI mode give you?

2) you have 3 drives are any of them using LVM or raid....and if so did you include
insmod (modulename) in your menuentry?

3) Can you post your menuentry....I suspect that if you used got the basic menuentry and that won't do it depending on your answers.


bootable, cdrom, grub2, sata
