ABIT BX133-RAID thermal sensor questions

[badpony]

First, are the temp sensors for the CPU and case built into the mobo because I get temp readings from both the CPU and the SYS1 (case?) monitors in the BIOS and with the included Motherboard Rx software. Both of these temps seem right on to me (about 33-35C for the CPU and 25-29C for the case) But, I get absolutly nothing from the SYS2 2-wire sensor mounted to my video processor which is connected to the mobo according to the owners manual. I triple checked the connection so I know it's right. Is there something I missed? Do I have to set up something in the BIOS to get it to work? If so what? All the SYS2 info is shaded out in the BIOS and I can't see a way to unshade it....... HELP....Mike S.
