Recently I got this motherboard. I've seen that there is a BIOS version without BUG of year 2000 and with Amd P75 CPU support, but in the upgrade process the BIOS that I should choose it depends the IO Core Logic of the mainboard: NS 332 or NS 311 / 312

1     Please find attached file of BETA BIOS for 486 PIO2 which will support Year 
2     2000.
3     
4     xxxxx101 --> for EPROM (Program the BIOS using an Eprom Programmer) 
5     xxxxx701 --> For EEPROM (Program the BIOS using a Flash Utility -> 
6     AFLASH3)
7     
8     xxxxCxxx --> NS 332 IO Core Logic
9     xxxxBxxx --> NS 311 / 312 IO Core Logic.
10     
11     Please refer to Year 2000 and LS-120 table.
12

What hell is that? How I can know the NS IO logic of the mainboard?

Thanks in advanced

This is referring to the sticker on your motherboard's BIOS chip.

At the image in the link, at the bottom right of the image (upside-down) to the right of the CMOS battery, the sticker has an 7-digit code (103C701 in the picture).

That's the (E)EPROM version. The I/O chip is the medium-sized rectangular chip to the left of the second PCI slot on that pic.

Another question. I've seen there is two revision of the motherboard, but I haven't seen any visual differences. How I can know what revision is my motherboard?

Yes, that's the 311 all right.
