I have an old PC which has the M537 rev 5.1 08/15/97-VXPro-UMC8670-2A5LAH09C-00 motherboard.
It has a connector for USB ports, but AFAIK it only works in USB version 1.0, which it's incompatible with the standard 1.1.
I've tried to install an USB PCI expansion card, but every time I plug the card in the motherboard, in BIOS POST appears the message "CMOS defaults loaded", and when I try to boot Windows 98 SE the system hangs while trying to install the driver.
I have tried three different cards in different slots and a BIOS update with the same result. I have also an Ethernet card, which Windows recognizes and successfully installs the driver, but after the required reboot I got an IRQ conflict.
Is my motherboard dead or I have to check something in the jumpers configuration?
