front panel error is driver related ...
as for slow windows boot times, you can remove start up programs / garbage / some services too
because windows sometimes try to initialize lan before the other peripherals, and if you still have an ide drive ... a 2.5" is sluggish vs an 3.5" unless you are in the 7200 rpm for both
for sure our 7404 is not fast on boot, i did push the fastest cpu (doubled the speed) i could find and max the ram amount
the su810 or Radisys can do 1.2 -1.3 gig celeron cpu, if you find the right fsb 100 speed multiplier, and i paid the cpu 25$ delivered ... they are not too pricey, be careful on the heatsink manipulations, you can break the top cpu die ...
for ram on the Radisys the mobo was very picky, i mixed a 100 speed and 133 speed to max 512MB, but it's not a problem, since they run at 100 speed
front panel need a driver
touch screen is normally an HID peripheral, did not ask driver in my case, but may need one ...
power pc board need a driver .....
but if in the end all is working ... and you did not pay a fortune in the end ...
