It will boot with a 1GB CF I have but that's very small and also very slow, the 4GB 133x CF I have doesn't boot but seems entirely readable once the system is booted from CD or HDD. Very odd as the adaptor is entirely passive, maybe there is some PC bios mode issue, I thought I had it working with the bios forced to PIO4 and no DMA but although the install seemed to go ok it didn't boot.

I already tried grub-install /dev/sda from the rescue mode of an Ubuntu 10.04 disk.

I got the Kingston to boot in the end but with a different adaptor and then only in a different motherboard! It was certainly much quicker than the USB stick 3 or 4 times better (46MB/s) and without the usb wait state overhead, booted pretty swiftly.

While trying to get it to boot in the real frontend I also found the PXE bios setting I couldn't see before so now it's netbooting and seems much quicker than it was with a local hard disk, server is pretty fast though.

Solved, well sort of...
