Works on HP T5710 booted from USB. The system is a bit short on ram at 512MB - 32MB for the CMS but I am posting from it with Web+.
Not very fast probably on par with a P3 or slow P4. It has a bit better IO subsystem than those however as it has hypertransport.
The only think I had to do to get it to boot was enable failsafe video… otherwise the screen would get corrupted. Failsafe is really slow though.
I have a TC1000 but boot hangs on it will have to investigate further it would be a really neat device to have Haiku on though.
