Unknown Device after Windows 98 install - What is it?

Hi

I've just installed Windows 98 on a Compaq Armada 1750 (previously XP was on it but I found it ran a bit slow).

I now have an unknown device that I can not get rid of (it was not there under XP) and am having a problem identifying.

I have done all the usual stuff of trying to udpdate the driver from device manager, and deleting the device to see if it is found again.

Device manager gives no information other than the unknown device is allocated interrupt request 03.

I found a piece of software called 'computer setup utilities' which contained 'computer setup' on th HP site that boots from floppy. This allows me to view various things including what devices are allocated which interrupts and shows me that something called 'Compaq 56v Global Internal Modem' is on interrupt request 03.

I've search everywhere for a driver for something under this name but have had no luck.

I would greatly appreciated some help. I have some knowledge but am far from an expert. Have I followed a logical route so far or am I on completely the wrong track?

Cheers

Bryn
