402cd io device irq conflict

I was trying to nstall a netgear card in this machine in the last few
months and then this error started showing up in the boot sequence 'IO
Device irq conflict" and then you are given the option to hit F1 to
resume. I removed the netgear card and drivers and even reloaded the
OP sys but the error still shows at boot up. I have even removed all
isa cards, and unplugged the ide cables to locate this error, but it
is still there even without an ops sys installed or ide cables
connected...any thoughts?
thanks mc

 

Replace motherboard CMOS battery. Should be a CR2032. If the battery
has been replaced recently, clear the CMOS, which remembers the IRQ info
and other hardware configuration data... Ben Myers

 

Does anyone know where I can find those 4 pin external battery
connectors for the cmos. Even compusa has limited items for sale any
more here in tampa...

does this pb 600 MB have jumpers for clearing the cmos?

Try this URL for PB600 info. The original PB web site is long gone, of
course, so you can't get the manual for it.

The J8 jumper, just behind the mouse port, clears the password, and
maybe the CMOS as well... Ben

 

Even better info about the PB600:

I was able to clear the IO device irq conflict at boot up, but when I
use the only pci slot available for the netgear card it gives a boot
up error at pci slot 3. I tried to manually change the irq in device
manager but no luck. I wonder if someone still makes an isa network
card?

The 402CD desktop system has a riser card with one PCI slot and three
ISA slots. Network performance is 1000% better with a PCI card, which
can operate at 100mbit speed. 3COM made a 3c515 ISA card that also ran
at 100mbit. If the OP already has a PCI audio card, then an ISA
Ethernet card is the only real choice.

Pity, but I scrapped all of my ISA Ethernet cards maybe a year ago.
Same with ISA Sound Blasters and ISA modems. At the time, nobody seemed
to want them... Ben Myers

 

Philo I do not see anything in the bios relative to setting the
irq........
Ben, I guess I'm a year late on needing an isa card, the pci slot is
not used, and the modem sound card is in the center isa slot. I ve
tried moving the sound card to a different location and re-inserting
thepci card but always get the same irq problem

Well, the early PB Pentium motherboards, like a lot of other early
Pentium and 486 boards, were among the first to have PCI slots. PCI
support in the BIOS was often primitive and incomplete.

Wish I could remember how to fix the IRQ problem... Ben Myers
