Hi Roberto!

   Will it let you into BIOS?!?

   If not, try seating the CPU over-and-over. About a year ago the industry "modified" the slot for Slot 1 so that SECC2/Slotket cards would work better. This has caused the front side pins not to completely contact the CPU.

   If you think it trying to work, do a manual default on the BIOS setting.

   PII 233 and some PII 266 are a bit different from earlier PII's. First, clock-locking was not used on these early CPU's. They can set from x2.5 to x4.0. And automatic voltage settings are abit of a wash on these as well. Later versions of BIOS have "a generation lost" in there background and rely on the much newer CPU's plug-n-play, and are test as suchat the factory. Defaulting the BIOS and manually setting up the CPU usually works.

   I have 2 PII 233 overclocked (one on a Alton MB with the same problem your having) using 100Mhz FBS. One at 300Mhz (100 x3) and the other at 350Mhz on an Abit MB, both with three fan heatsinks. So far, both systems have been up almost a year without an issue.

   Hope this helps,
   Michael
