Shuttle Sk41 won't boot

i've just bought a new pc shuttle xpc sk41 socket a barebone system c/w VIA KM266 DDR m/b + LAN +6 channel audio, and added amd athlon xp 2400 (266mhz), 512
mb DDR333 (PC2700) ram, NEC ND-2500 8x dvd +/- r/rw, shuttle 6in1 card reader, asus radeon 128mb graphics card, 56k modem.
when all installed Aida32 told me I only had a amd xp 1800+ to which i was confused.

after being told in the bios to change it i found a way to do so and set the CPU clock from 100 to 132(this was the highest allowed). and my aida showed I had a 2.4 amd, but I didn't feel this was right and thought i may have done it the wrong way. I subsequently went back into bios and changed the DRAM clock settings without realising that was nothing to do with the CPU.

now the pc won't boot, i turn it on, it sound slike it starts but nothing but a blck screen, i press reset and it starts again and this time the monitor is on but its freezes after it tells me what bios(fx41s026) i have, then the processor it freezes before or during memory testing and it won't let me press DEL or ESC to get into BIOS and reset it or to cancel it.

my question really is how can I reset the bios to original settings if i can't get into it?

p.s. i don't have a floppy drive as its a card reader instead.


also the problems wiht the monitor not turning itself on right away were present before i fiddled with bios and i often had to press rest just for the monitor to disoplay anything.

any clues?

well after that rush of responses i thought i should update you on my progress - all is fixed. I learnt from a friend that a mobo should have a jumpers on it to reset a bios. this was something that is so obvious now but yesterday pulling my hair out I had no clue, google didn't seem to produce any decent results for any of my queries and usenet and forums seemed to close ranks and refuse to answer my query. oh well crisis averted.
