[mythtv-users] diskless Mythtv USB

I have the same motherboard.
I have been working on installing FC5 to a THinkpad T40 where the CDROM 
is broken.

Regarding booting from USB or net, check out


where the poster discusses installing FC5 to a Thinkpad X41 (which has 
no optical drive).

I suggest that you actually check your USB key by writing diskboot.img 
to it and attempting to boot the motherboard. (It will launch the Fedora 
install process). I have tried 3 different USB memory sticks and 
consistently get a 'Boot Error' on the Thinkpad T40.

I am about to set up a PXE network boot setup. I have seen it stated in 
different places that you need to have the boot server running as the 
DHCP server and also that you do not need the boot server to also be the 
DHCP server. The page linked above gives details for the dhcpd.conf file 
which clearly show that the DHCP server can serve static IP addresses to 
specific MAC addresses. This implies that the DHCP server can be on a 
different machine..but your Linksys router is not likely to have the 
flexibility to do it! I know that mine cannot.

So you will likely have to turn off the router's DHCP server...but then 
again, in a small network, why would that be a problem? Just go all 
static and get the DHCP server to serve up a static address. A dynamic 
address is really only useful for things like wireless... but a static 
address is a lot safer for wireless especially if you add a MAC address
