hi everyone

I had a old P2 machine with me in which i try to install usb card. but when i inserted the brand new PCI USB2.0 (4+1) card in pci slot, the system nor show any display neither it boot up (as there is no beep). but when i remove this card system is going perfectly alright.

I had used the usb card (2 port) in this machine about 3 year back and at that time it used to work perfectly fine but i don't have this card(2 port) with me now.

I had installed this card(4+1) in my amd sempron machine and it work perfectly fine.

Please Help.

I suppose that the problem is in PCI bus version. Please check your motherboard documentation and your PCI USB2.0 (4+1) card documentation.

Also after boot screen when usb card not installed it shows

PCI DEVICES:

PIC ONBOARD PCI BRIDGE

PCI ONBOARD USB CONTROLLER, IRQ9

PCI SLOT 3 ETHERNET, IRQ10

PCI ONBOARD BRIDGE DEVICE

PCI ONBOARD IDE

PCI BRIDGE VGA, IRQ11

at IRQ settings in Bios there is only 2 option set to either PCI or ISA. I had tried to set it to ISA and then Back to PCI but the problem still exist.

I dont find any thing like latency in my bios setting few thing related to this i noticed is -

1. Master Lat. Timer : 40H

2. DMA-0 to DMA-7 Type all set to "Normal ISA" no one is set to "PC/PCI"

3. Power management : disabled

4. Legacy USB KB/MOUSE support : enabled

5.PCI latency timer (PCI clock) : 64

6. DMA Channel 0 to 7 : all set to "PnP"

i think this could help

The description does not contain any information about the PCI bus version required.

Here http://www.syba.com/support_download/faq/08/index.html you can see that their USB 2.0 cards are PCI 2.2 compliant, Intel 440BX, 440EX, 440LX chipsets are PCI 2.1 compliant only. If you have any of these chipsets you have to find USB board that is PCI 2.1 compatible.

The motherboard, chipset and many other useful things you can get using Everest:

Everest Home, build 475 - the latest beta, no longer developed.

Everest Ultimate, build 865 - the latest beta, 30-day trial version.

Yes i think this was the problem. i got my card replaced by another card (i think slightly old version) now it works.

thanks a lot for the support

When the pc is checking your ram you can hit the pause button. You will see the bios information at the bottom of the screen. From this number you can trace the manufacturer & model number of the motherboard. You should then be able to get the owner's manual / specifications.

There might have been a "reset PCI config" option or something like that in the BIOS that might have helped.
