MisterE,
As far as I can tell, the mobo from Centrix is the same as Andara's, but has the cd-in, modem-in and aux-in connects in front of the game/midi port. No need to slip it under the AGP card, let alone PCI slot1. The bios screen was different also- comes up with a Micron logo screen and doen't show what bios was doing until Win boot. You can press a key and the bios boot will show.
Anyway, the bios chip is labelled 1.02 but, in the cmos setup utility, lists as 'micronpc.com bios version 1.04'. Has zilch for options. The Advanced, Advanced Bios Features tab only gives the options of boot device order and numlock status!!!- under Advanced Chipset Features it lists only AGP aperatue size and mode!
Anyway, seems way more stable than the Overstock version. May be due to WinXP vs Win98SE, but haven't upgraded this pc yet to check. I still can't do a 'suspend to ram' sleep mode without lockup on either of my Overstock bb's, the second's (sent up north to mom-in-law) power supply is acting buggy. Maybe I just lucked into a good Centrix system.
edit: BTW, you can pick up one for $79 (+19.95 shipping to OK!) at
Andara site
edit2: 950 tbird doesn't seem to matter with this mb, never tried >=1 ghz. Why don't we see 133a bb's for this price by now!
