This board does boot, either from CD or USB, but not able to setup BIOS or go further where a keyboard is required. The key board and mouse tried are both PS and USB port varieties and work fine on another of the same model motherboard. Loaded Bios #1715 using CD and remove jumper. I have reset BIOS by removing battery and power for an hour, Loaded Bios # 1761 (latest) using CD and remove jumper.
Here's what it does do from power up:
1: No memory, keyboard, mouse, or video card, power up - 3 long beeps (expected)
2: Add 1G memory, power up - no beeps (expected 1 beep - no keyboard)
3: Add video card, PC or USB keyboard and mouse, power up - Bios setup screen appears with the flashing numbers lower right corner, normally. "F2" tapping has no effect, Numlock is on, mouse laser on, a flash something ...autoconfig... upper left corner of screen (normally not seen), hangs at screen ...GE Boot Agent v1.3.34... , ...PXE... The language on the Bios setup screen seems to be a different dialect of English, of maybe even French??
, initalizing and establishing link. (Ethernet not connected or boot set up)
4: If a bootable CD, or USB flash drive inserted, will boot, and get to a screen where keyboard input required. This is both with Clonezilla and Linux Knoppix live CD.
Other things I have done:
1: Tried various power supplies, at the moment hooked to a PSU from a working D845-WN motherboard, just moved the power cable (including the 4 pin Pentium) and IDE CD drive with no change.
2: Tried several other mouses and keyboards, all interechanged to several other computers. All this hardware had worked previously on this board, and an identical board.
3: Compared with the identical board, the mouse and keyboard port resistances without power, and voltages with power to all pins. Also using logic probe checked for activity. Nothing out of normal range was detected. So the wiring to the first chip (Winbond) and at least to the first, I'll call transistor is OK, if there is a fault, could be in the chip.
4: After booting the identical 2nd board into Windows XP SP3, plugged in USB mouse and keyboard to confirm that all 4 items would function at one instance, which they do. Thinking if one was recognized, it's mate would be disabled.
6: Ran Linux (Ubuntu) memory check on the memory, in a 3rd computer with no issues.
What I find very strange, is apparently the USB is working OK since it will boot. I would think, that both the USB mouse and the USB keyboard drivers are loaded from BIOS, along with the code for the boot. Then lead me to believe the fault was in the Bios code, and decided to reload the bios with no changes.
I have seen where Bios set for network boot could cause this but thought resetting Bios would correct that.
Any comments appreciated.
