BIOS Updates forum

Hi all, I have a board with PCI-to-ISA bridge [ITE8888 chip]. I am customizing the BIOS for our board. Actually, I don't want O.S to see the chip at all. Is there anyway I could disable the chip thru' BIOS. I know by removing the IDSEL resistor, we could disable the chip. But I am just wondering whe...

Hi ALL, I just want to write a CPU diagnostic program. 1. What are the tests has to be implemented for minimal diagnostic? 2. Is there any chance of particular hardware part getting failed? ( Like Adder, Floating point unit, Branch Prediction Logic) 3. How to test the differnt execution units of a S...

Hi all,

Does anybody know the way to access the application processor in a dual processor system? Or the way to send some particular commands/instruction to application processor?

Thanks In Advance

Hi, Could you explain what do you meant by " Messed-up BIOS chip "? Do you mean entire chip has gone bad or it hangs at some stage or what?? If you are not sure, just plug the PCI/ISA check-point card [displays value from port 80h] and see what value you are getting at the end. Depends the value, we...

HI,

Is AGP interface one-way communication or two way? I mean, whether it can be used to send/receive and receive/send data?

I think, its more or less PCI. am I right? How BIOS detects AGP devices? Is it as same as PCI or ???

Hi,

Thanks again for ur reply.

What are all the things should be considered to make a non-graphics agp card as per software and hardware perspective?

Hi all, Thank you for your reply. www.agpforum.org/downloads/richards.pdf Get this .pdf file and just look at page number 5. This pdf file is from Microsoft. They specifies something about AGP's other functions on that page. What my doubt is, why don't we develop someother card [like agp card] which...

HI, As we know, AGP is faster than PCI bus. I'm just wondering whether AGP can be used to someother purpuse [apart from display] like PCI devices? :?: If so, please let me know what are all the things can be done and what are all the things should be considered to do that. Thanks In Advance. -Raj.
