It has two 3Com ISA cards, a Etherlink Fast 100 Mbps (driver 3c515) and Etherlink III 10 Mbps (driver 3c509). The router is connected to a cable modem through the 10 Mbps ISA card and the other one interfaces with a switch-hub to the LAN. I am considering if due to the limits of the bandwidth of the ISA bus if it really is worth to have a 100 Mbps to the LAN interface in the 486. If I use that 100 Mbps ISA i.e. in a Pentium III the performance would be similar to a PCI NIC? Apart from that I have two kernels, one the default kernel using modules with RH 7.3 and a monolithic 2.4.22 compiled with the drivers. I am having problems to configure the parameters in the monolithic kernel for using the two NICs in the /etc/lilo.conf because the system detects the 3c509 card, but not the 3c515. What is funny is that If I boot using modules, it uses isapnp, I cant make them work either, but i= f I reboot to the monolithic kernel then It suddenly appears to detect th= e 3c515. If I shutdown and boot again the monolithic kernel, says that no 3c515 card found...I=B4m stumped. Anyway I dont know if the 3c515 is trying to use the wrong IRQ. When I succeed to recognize the 3c515 card (using the trick of booting the modular kernel first), it seems that IRQ 10 is fine, but uses the DMA 3 channel...Is this right? What I do it=B4s to set the IRQs and IO base address in the /etc/lilo.conf file, but I am wondering if those setting= s are right. I downloaded the configuration tools but I only get the IO base address and the IRQ in the 3c509 card and only the base address in the 3c515 card. Any hints?
