Hi all, I have a rather old (OK, ancient in PC terms) Pentium Pro
machine which I use for messing about with and doing experiments with,
which has an Asus PI-XP6NP5 motherboard. I've noticed that the board
has a set of pins for connecting USB sockets, but no indication of what
the pin layout is (I've looked at the pdf manual on Asus's website, with
no luck.) Having working USB on it would be nice, to make it a slightly
more useful dinosaur, and I know the USB controller works because Linux
successfully detects it on boot, but I don't know what connector it
wants. Since it looks to be the same 9-pin header as found on current
boards (pin 9/10 end .:::: pin 1/2 end) I might just try connecting new
(or new-ish) USB sockets to it, but I was wondering if anyone knows if
it will be the motherboard pin layout or not.

Thanks,
Andrew

I *used* to have a PI-XP6NP5 motherboard with USB connected.
Unfortunately I sold it - but I *think* the pinout matched the 9-pin
layout shown as Example C on this page:

http://www.usbman.com/Guides/BelkinM...e_assembly.htm

I recall having the same issue locating pinout documentation, so I
checked the motherboard header with a DMM to make sure I had correctly
identified the +5V and Ground pins. I recommend you do the same - mixing
up the D+ and D- pins is unlikely to damage anything, but +5V on the
wrong pin probably will.

It surely looks very similar to the connectors of today. The t2p4 was a more
popular motherboard of that time and is similar in a lot of ways (usb not
mentioned in manual except from bios setup).
Here: http://makeashorterlink.com/?Y1DA258BC
they have traced the pinout of that mobo. It would surprise me if it was
different from your board. If you compare pinout on t2p4 with today's board,
and they are similar, it will further strenghten the hypothesis.

On the other hand you could throw caution to the wind and go down the shop
and blow $25 on a 4 port USB2 PCI card.

Yes, particularly since the motherboard is almost surely USB 1.1. A
separate USB 2.0 board will be much faster.

Well yeah, but when I can get the parts for nothing via Freecycle, it's
worth having a go :-)

Sure it's faster, but it really depends on the intended usage. I've
meant to use the USB pins on my old T2P4 board just so I can hook up a
USB mouse, in case my old serial mouse dies... For this a USB 2.0
interface won't make any difference.

That's true. A USB2 board will be faster than a USB1 board and that is
exactly why you would fit a PCI USB2 card in an older computer.

I still have several T2P4 systems. I set up the T2P4 native USB adapter
on one of them and it worked OK for some of the early USB devices. The
T2P4 Intel HX chipset was wasn't really optimized for USB as it wasn't
released at the time this chipset was developed.

I have one of the T2P4 Asus USB adapters but I would probably go for an
addin 1.1 or 2.0 PCI card.

Hi Chas!



You think a 2.0 Card can make the T2P4 full USB 1.1 and 2.0 compliant.
Let´s say in NT< or Linux. ?

Is Mouse (USB of course) and Joystick working with the T2P4 onboard USB?
