||I had the manual, but no CD for drivers for my motherboard (bought January 2000). I read "PC 100" on the manual & chipset, so I tried PC100.com site. I was informed that PC-100 is a specification (not a company) and to try PC Chips for a potential manufacturer. The PCChips.com site had the audio, video, modem & USB drivers I needed---and which I zipped & uploaded here. I found the audio 8738 number on the C Media, Inc (CMI) Sound Pro chip. I found the video SiS 530 number on the PC 100 Oak Technologies mainboard chipset. I found the DAA V90 on the PC Tel HSP56 modem.
