To summarize : install, reboot in rescue mode and create a initrd with the USB modules : mkinitrd ––preload=ehci–hcd ––preload=usb–storage ––preload=scsi_mod \ ––preload=sd_mod /boot/initrd_usb.gz 2.6.9–xx Since 'modprobe usb–storage' does not wait for the USB drive to come up, you may need to add a '_sleep 5_' in the linuxrc script of initrd as explain on Simon Ilyushchenko <mailto:simonf at simonf.com> page : http://simonf.com/usb/#older. -- Pierre-Francois Honore -------------- next part -------------- A non-text attachment was scrubbed...
