Basically, the srom only contains mac address - no check sum nor media tables. You need to by pass the checksum checking and eeprom parsing in the driver code. In addition, I have to reset the tulip chip at the board startup time. I use pmon to do the downloading. Pmon must have set the chip in some state that the linux driver cannot successfully re-initialize it by default. I also layout the PCI memory space idential to the physical memory space, ie., system ram starts from 0. I was concerned some drivers don't do address translations between these two address spaces. I actually have a DDB5074 board myself. I can try it out myself, but I am a little lazy to do that - not sure if anybody is still interested in that board. > > port, IDE disk, PS/2 keyboard/mouse, Voodoo3 2000/3000 PCI graphic cards > > (framebuffer driver). > > Cool!
