Can't boot GS12 into BIOS

Archived from groups: alt.comp.periphs.mainboard.tyan (More info?)

Hi All -

I can't get my barebones Tyan GS12 to boot into BIOS.

This system has Phoenix 1.05 BIOS. I connected a monitor, PS/2 keyboard
(via USB-to-PS/2 adapter) and USB mouse and turned the machine on...
The GS12 LCD display says:

PhoenixBIOS 1.05
H/W Initialize

and then after about 30 seconds the GS12 shuts off. Nothing shows up on
the monitor. I hit F2 a few times but still nothing happens. Monitor is
appears to be correctly connected - because it does "blink" briefly
when I push the yellow ON button on the GS12.

Installed hardware:

- CPU: Intel P4 "Northwood" 2.8GHz, 512K L2, 533MHz FSB
- RAM: 2 x OCZ 1024MB, DDR400, PC3200, ECC Reg, 400MHZ
- HDs: 2 x Western Digital SATA 250GB 8MB Cache

Does anyone has any ideas how to get into the BIOS on this Tyan GS12?

  1. Hi Scott --

    I had the same problem, and I found it was the CPU overheating. The heatsink, which screws onto the motherboard with four sprung screws, requires a surprisingly tight turn in order to make full thermal contact with the CPU.

    I was a bit hesitant about this, and I didn't tighten the screws enough. It's also worth following the guidelines in the manual about tightening the screws in a diagonal pattern, that is: top-left, bottom-right, top-right, bottom-left.

    Hope this is helpful!

  2. I also have this problem, and I have try to tightening the screws, but it still says "PhoenixBIOS 1.05 - H/W Initialize". Does anyone have a solution for me.
