If you plug the USB drive into a Windows system does it show as fixed or
removable?  If the latter, try using Lexar's BootIt! Utility to switch it to
Fixed.  After that, remove the 3Ware controller (and any other disks) and
try installing to the USB drive again.  If that works then you can plug
everything else back in after you've installed.

If that doesn't work then it's probably not possible to install to USB at
this time.

Subject: [OF-users] USB key and grub install issues


Hum, tried an install to a USB key on a motherboard with two 3ware 7810
controllers, each with eight 320GB PATA drives attached. The intention
was/is to use software RAID as it is more performant than the hardware
raid of the controllers.

The first issue was that although the Anaconda installer loads the
usb-storage module, and if I grab a shell and do an fdisk -l it shows
up, the key is not available as an install target... Testing with CentOS
5 and it shows up. Not to much of an issue I can install to one of the
PATA drives and haxor it up to USB key boot.

Then I hit another issue, looks like grub gets really upset if there are
more than eight drives, and refuses to install on drive 17 which is
where the BIOS/motherboard is placing the USB key. This sucks somewhat.

I can again haxor this up with a better boot loader (I always had a
dislike of grub) but perhaps this should be looked into for possible
future feature improvements. I guess quite a few people might look to do
something similar.


JAB.
