How to identify the BIOS version    

Upon boot-up, the 1st line appearing after the memory count is the BIOS version. It is usually in the format:
A6590VMS V5.2 091096 where:

1st digit refers to BIOS maker as A = AMI W = AWARD
2nd - 5th digit refers to the model number of the MB (here is MS-6590)
6th digit refers to the chipset of the MB (example: V = VIA, S = SiS, I = Intel, A = AMD/ATI)
7th - 8th digit refers to the customer as MS = all standard customers (ie retail board). If these two digits are NOT 'MS', then you have an OEM board and should read this topic
V5.2 refers to the BIOS version.
091096 refers to the date this BIOS is released.

If you see a logo instead of the POST screen, press [Tab] key to display. You can press the [Pause|Break] key on your keyboard to halt the POST screen if it disappears too quickly for you.

How to identify your motherboard model version and ERP number
Motherboard model is located between PCI slots listing both the model name and model number

Model name: KT6 Delta
Model number: MS-6590

When posting your specs, please use the model name, not the model number, as the model number can refer to several different boards. Click >>here<< to see what we mean, if you only talk about a MS-6590.

The ERP number is located on the side of the last PCI slot near the edge of the motherboard

ERP number: 010 as listed under M/LOT
