Hi ! At work on my HP Kayak XA Workstation (450 MHz PII) all PCI cards share the same interrupt, this causes slowness, only 46 KByte/sec. throughput, although being configured as 100 MBit full duplex on a Cisco Catalyst 5509 switch with IOS 4.4(1). The BIOS lets me enable PnP capable operating system and I can manually enable the bus master dma bit for every PCI slot. When I do both (enabling PnP OS and the DMA bit) the AHA2940 and the ELSA PCI Graphic cards get different interrupts (hurray) only the network card now doesn't get any irq :-( I read in the sources, that the tx driver doesn't have DMA support. Might it be the case (the only idea I got over the weekend), that I have to disable the busmaster DMA bit in the BIOS for the PCI slot where the SMC network card is installed into ?! Is there perhaps something other wrong with the tx driver or is it the BIOS of the HP Kayak from which I already heard bad things. What do you think.
