Installing Fedora 10 on a ThinkPad T60
The news is that almost everything I tried works out of the box. Just make a Live USB stick and install normally.
I haven't tried Ultrabay hard disk bays under Fedora 10, but in Fedora 11 they mostly work, except that the pre-eject button isn't hooked to anything by default. The tips in [How to hotswap Ultrabay devices] can be used to gracefully unmount, with some minor changes.
PCMCIA to ATA adaptors (that, for example, allow compact flash cards to be attached to the PCMCIA card slot) have been problematic in the past, but appear to work fine now.
