You have an Abit board, so this should be simple enough.
When booting, you should notice a prompt indicating what key to push to enter the BIOS. It should be the escape key if my memory is correct. If you do not know what you are doing, copy every setting to paper!
Enter BIOS, find the section labeled SoftMenu, then change the front-side bus setting setting.
You have a 66MHz bus processor. The processor has a fixed multiplier value, in this case 6.5x.
66x6.5=433MHz
Without getting into the technical details, I recommend trying 75MHz to start with, then move up in 1MHz increments until the systemf fails to boot.
Upon boot failure, you know the last working FSB frequency. Find in your manual the method to reset the board's BIOS. It will be a jumper upon the motherboard.
Reset the board, then go back to the BIOS. Reenter all settings as wrote down earlier. Set the FSB a few MHz below the failure point, and you have achieved an overclock.
You may also need to apply additional core voltage through the BIOS SoftMenu interface. Unless you have an aftermarket heatsink/fan cooler, then do not exceed .2 volts over stock settings. Excellent cooling is a key requirement to overclocking.
Even if you seem to have a stable system upon booting, it may fall to boot into Windows or run stressful programs. You have three options: lower the FSB, increase the core voltage, or improve cooling. The last two options often work best when applied in conjunction.
The BX6R2 also lacks bus locking, so avoid the 80-83 MHz front-side bus range. This will operate you PCI and AGP buses way out of spec, thus possibly damaging your hard drive and/or video card.
Now do you want my real advice? Pick up a Celeron 1100 Socket 370 FCPGA retail box processor and save yourself much effort and trouble.
The retail version can be found for around $40, and the retail chip comes with a heatsink/fan cooler already provided. You will also need a FCPGA slocket adapter ($10-15) to convert the slot interface to the Celeron 1100's socket interface.
Do not purchase any higher Celeron, as higher frequency versions are FCPGA2 models.
Follow your motherboard's manual for installation and configuration. Or best yet, most local shops would probably perform this upgrade for around $125. This is your best bang for the buck performance option with the BX6R2.
My recommendation also assumes you have PC-100 (or better) memory. A local shop could check that easily enough, and if PC-100/133 is required to upgrade, compatible PC-133 SD-RAM memory can be purchased for dirt cheap prices these days (<$20 per 64MB).
The problem is all the small variables and aspects you have to account for when overclocking. My book is a condensed guide, and it weighs in at 272 pages.
Overclocking is not for the faint of heart, nor is it recommended for anyone lacking detailed hardware knowledge.
Hope this helps,
