I just got free machine with a PII 266 in it and I am wanting tp upgrade it. The board has the SiS 620 chipset on it, but the motherboard manufacturer is no help. The chipset supports 100 mhz bus, and the original PIII but I want to know if they support the newer Cu mine PIIIs. If anyone has any information on this chipset, please let me know. P.S. the SiS site is not really any help as all they say is PII and PIII. Thank you.
