Hello good morning.
A few months ago I bought a SLOT1 DFI (ITOX) PA61 rev.D2 motherboard.
The board came without the BIOS chip. I have downloaded several versions of BIOS, but none of them work since they are not from the BIOS rev. D2.
Is there anyone who has a BIOS dump of version D2.
Thank you so much.
This image is downloaded from the internet and is to show the reference of the Chipset ICs. On my motherboard the chip next to the processor is covered by a heatsink and the reference cannot be seen.
Is there any activity/codes on the post card if you have one?
I will prepare the motherboard for a test. I did it but two or three months ago. I do not remember the codes in the testing board.
According to my notes this is the BIOS I had on a PA61 rev.D2.
That board later died so I can't test it, but it did work for a time.
Thank for your support.
I have prepared the mobo for the test requested and I checked in the testing board that the 3.3v are missing.
Therefore, first I have to check what is the problem with the 3.3v. I did not see it in the first test.
Thank you and regards.

I did the following measurements:
AGP SOCKET
+12,0v. , +5,07v., + 3,32v., present.
CLK= 75 MHz
PCI SOCKET
+12,0v. , -12V., +5,07v., present. + 3,32v., NOT PRESENT
CLK= 37MHz
FRONT PANEL
HD LED = +5,12 present.
G LED = +5,12 present.
ATX-SW= No voltage present
G-SW= +3,50v. present
RESET= +5,10v. present
Why is available 3.30v in AGP socket but no in PCI socket?.
Probably 5v only pci slot, you could check the 3.3v pins to see if they are connected to anything. https://pinoutguide.com/Slots/PCI_pinout.shtml
since board came without a bios chip, probably it was dead and the owner took out the chip and sold it.
I have checked the following:
SLOT 1 SOCKET
ALL PINS VCC1.5 = 1.5v.
SEVERAL VCC CORE = 2.06v.
PICCLK= 14.3 MHz
100/66# MHz = 3.09v.
PCI SOCKET
I have revised all 3.3v. pins and none of them are connected in the track side but maybe they are connected in the components side ???
Maybe the motherboard was dead and owner removed the BIOS chip.
I am going to program the BIOS with the BIOS dump delivered by Shamino and see what happen.
Motherboard does not work. I can see the reset led in the diagnostics board but nothing else.
The motherbard is dead, probably the chipset (one of the VIA chips)
A motherboard for spare parts.....
Thank you.
