That is a totally different thing to which I said nothing! No Linux driver will help there, in fact no driver at all will help there if your BIOS doesn't support booting from USB media.

How do you think your kernel boots, given that the ide/sata/scsi drivers and the drivers for the file system you use aren't compiled into the kernel? They're loaded via the initrd and that incorporates the drivers that the install determined to be needed. I haven't tried with USB, but with any other boot media I've encountered. If the kerrnel can boot off that media, it can also load the initial ramdisk and that in turn is easiest built by using mkinitrd.

Exactly. If grub loads from the usb device, it doesn't have to be told about the usb device. Chicken or egg thing.

Consequently, if the BIOS doesn't allow booting from a USB port, then you can't boot directly to the USB drive. It make no difference what it on the end of the USB cable, it is still goes through a USB port. You would have to create a boot CD that would boot a minimal kernel that was smart enough to know about USB and then boot from the USB drive itself. You might find more details at pendrivelinux.com. I believe there is also a openSUSE howto on this subject.

Most likely just a matter of editing the right grub entry and the fstab on the external. I havn't tried it, but it does not sound that hard. Default kernel doesn't have everything necessary for USB disks... the USB module has to be loaded up...which then creates a chicken and egg problem. So, part of the solution is recompiling the kernel to include the USB module (and all the others which the USB module depends on). Because USB ports are more common than parallel ports now, and especially USB devices, I would like to see the USB module compiled into the default kernel, rather than USB being a "2nd class" form of I/O. As long as it's still maintained as a module, the embedded systems projects can still choose to leave it out of their default builds if they so choose. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
