Hi, i need to know how to find the bios/gap on my V4. I did a srch and found info on the bios, but not how to find it. I want to put in an apple chip (already have 2.2) and want to know which kind to get, 40 or 20/30. Any help appreciated. Thank you.:)

anybody...

Well, if you have a V4, the Apple should be fine with any of the BIOS. (Here is precisionmods chart) Their Ultra 2 is the apple I believe

this one shows where the BIOS is on v1 or 2 but the chip would look the same on v4, just go look for the # on the chip

Sorry about that, I forgot, but thanks for the information!!!
