BIOS Settings

Here are my Recommended BIOS Settings for those of you who have been having problems with the TX5N/TX5 and higher bus speeds. Below are my recommended settings for bus speeds < 66MHz, 75MHz, and 83.3MHz. If you are using Non-EDO RAM, then use the settings the in the 2nd (Non - EDO) column, if you are using EDO RAM with a 50/60/66MHz bus speed use the 3rd (66MHz Setting) column. If you are using EDO RAM with a 75/83.3MHz bus speed use the 4th (75/83MHz Setting) column. Finally, if you are looking for the safest and most stable setting, use the last column.
