bios fiasco

My bios has been underclocking my cpu for a while, so I was trying to reset the cpu ratio in bios. I have an athlon xp 1800+ which can run at 1.53gHz. Mine has been running at 1150. So I was browsing around the bios to find the ratio multiplier, which I found. I changed it from auto to 10x. (The range was 6x to 14x). My computer basically doesn't boot any more, not even to a degree where I can get back into bios to reset it to auto. My monitor simply blinks its power save light which is what it does when the compter is off. The power switch does not respond. The restart button makes the cdrom lights reset, but I'm not sure if it does anything else. I've tried unplugging it for a while before restart, though it makes no difference.

I don't think I could have burned the cpu out unless the 10x ratio was a massive overclocking attempt (which I doubt because the cpu was top of the line when the mobo was mid-range). But I can't think of any other reason I would be completely locked out of my system, so maybe I am out of luck. Any suggestions would be more than welcome. I bought and assembled the parts of my computer 2 years ago with a few upgrades since...

To reset you will have to clear the CMOS, check your M/B maual.

The 1800+ is 133 fsb (double pumped to 266 blah, blah). So reset the "FSB clock" from 100mzh to 133mzh to get a speed of 1800.

Here is their setting for the XP 3000+ :

Note the fsb clock is 166mzh for the "fsb333" processor.

To clear cmos - pull the cover off the case, (unplug the machine first), disconnect the internal ATX power connector from the MoBo, move the CMOS jumper to pins 2&3 for 5-6 seconds, rejumper CMOS on 1&2, reconnect internal power connector, plug the power cord into a recepticle and boot up. Voila...
