hello, i have 3com etherlink iii 509b isa card that refuses to let me change its port or irq. also the only way i can get the card to talk on the network is to put my usb mouse on the same irq and wiggle it around really fast when i'm trying to receive or transmit. initially i could change neither the irq of the usb mouse nor of the ethernet card. i have turned off pnp in my bios and i can now move the irq of the usb mouse. however, without the wiggling mouse sharing its irq, the ethernet card with not work.
from what i can tell by gleaning the 9fans archives, the 3c509b is quite a troublesome card. i found rumors of a dos utility that would convince the card to change its port and irq. i think this leaves me with two questions. first, where do i find this fabled configuration program? googling has proved fruitless. second, is fiddling with the port or irq even going to fix the problem? as far as i understand, if the card has its own irq staked out, it should just go on its way here is what is printed on startup: #l0; elnk3: 10Mbps port 0x300 irq 10: <ethaddr> #U/usb0: uhci: port 0xEF80 irq 12 #U/usb0 was initially at irq 10, but after disabling pnp in bios, i was able to move it to 12 -- m ps, i have a very limited understanding of what an isa card's port and irq even do. if i said anything that doesn't quite add up, that's probably why
