5-2 Frequently Asked Questions
Q is for question. A is for answer.
Q: Why can’t the CPU frequency be adjusted to 100 MHz ?
A: The BIOS will automatically detect the CPU frequency (66MHz or 100 MHz).
Therefore, if your CPU frequency cannot be adjusted to 100 MHz, then your CPU
may be 66 MHz. In BIOS “speed setup,” there are other frequencies, like 75
MHz, 83 MHz, 103 MHz, 102 MHz, 112 MHz, 133MHz. These are for internal
test only. No guarantee is provided since this is not included in chipset
specification.
Q: Why is my system not stable with 100 MHz CPU?
A: There are many reasons for this condition. One of the most common is that
SDRAM does not match PC-100 specification. When system is operated under
100 MHz, in addition to 100 MHz CPU, SDRAM must be PC-100 DIMM too.
Q: Can I install another VGA card on this main board?
A: NO, this main board has VGA function on board with the chip “MPACT™”.
