a7n8x deluxe

Anyone change their default settings?

You can tweak just about anything you like on that board, but I sometimes turn off the firewire controller to speed up the boot process (if you don't plan on using it).

That is almost always a good idea bloom25. I turn off my COM ports, LPT port, 1394 port/hub in the BIOS.

It does speed the boot process and free up IRQ's.

is it really Skuzzy?

i got sooo many shared IRQ's and those lone COM / printer ports and carp.

any you would leave up "just in case" ?

Six,
What's speed of proc your using?

What does your bootup screen report for speed?

By the looks of it, I'd say it's only runnin @ 1100mhz

If it's suppose to be a 333 proc than fsb should be 166.

Could be wrong but thats what it looks like.

The mobo manual says 6 usb ports. I have the 4 in back and the two in front connected to the board. I have a card with 4 usb slots that plugs onto a PCI slot. If I turn off the COM ports, LPT port, 1394 port/hub in the BIOS, will the free IRQ's let me run the extra usb ports on the pci card?

I found 1394 and disabled it, but i'm a little confused with what the COM and LPT ports are.

To make sue of those free IRQ's you have to turn off the devices before you install the OS. In some cases, you may have to manually assign the freed IRQ's to the PCI bus in the BIOS.

The COM ports are the two serial ports, and the LPT port is the printer port. All ATX class motherboards I have ever seen have these devices on them and the BIOS should allow you to disable them.

I do not need the LPT port as my printer is a network printer, and the COM/serial ports are a waste of motherboard space these days, unless you use one for an external modem, but you can still disable the other one that is not being used.

That Pic wasn't showing for me last night.

You definately need to set your FSB to 166 MHz for a 2500+.

Your COM ports are located right under the firewire device you disabled. Onboard serial port 1 and 2.

Skuzzy or Bloom25,

Is there an easy way to manually assign a card to an IRQ, don't some share with the AGP port? Would you explain in plain terms how to manually assign a IRQ? We all appreciate your replys, and your time on this bulletin board.

Thanks,
Thorns

Depends on the motherboard/BIOS Thorns.

Most allow you to assign an IRQ to the slot and set the type (legacy or PCI) of IRQ, but you need to know which PCI slots are hardwired to share interrupts with other slots/devices.
PCI only has 3 interrupts available to use and they can be any number in the newer motherboards.

Typically the PCI slot closest to the AGP slot will share interrupts. Most ASUS boards have slots 2 and 5 sharing. Then there is another slot sharing interrupts with the USB ports. Typically you only have 2 PCI slots with dedicated interrupts today, maybe 3.

In the system BIOS it may show the PCI slots that are sharing with each other, but that will be about it. You have to refer to the motherboard manual to find out what else is shared and with what. ASUS normally has a nice chart showing which slots are dedicated and which ones are shared and what they are sharing with, in their manuals.

This is something you should take time with before installing the operating system, as it is a pain to do after the fact and could leave some dead drivers laying around.

Ok, Thanks for the explaination.
