- I could made a test ISO (archiso based, 2.6.28) with grub2. This boots fine in virtual machines (like virtualbox or qemu). But on real machines the cdrom (biosdisk module) wasn't found. I never see cd0 on real hardware, only the harddisks (looked with ls when ls-module is aktivated). I tried question on #grub in IRC, but no answer. (With the ata module the cdrom could be handselected with low speed, but this is not practicable...)
This is interesting: On many BIOSes, grub 0.x is unable to find the CD drive and thus many people want us to use isolinux. From what you write here, it seems that you can access the CD drive through another than the BIOS boot device method. It doesn't matter that access is slow, it only matters that we are able to load the kernel and initramfs on a greater number of machines. IMO, this is worth looking into.
