With the latest version you sent I got it compiled and working. As far as I can tell from short tests it looks good (eth2 is tg3): CPU0 0: 79344 XT-PIC timer 1: 2428 XT-PIC keyboard 2: 0 XT-PIC cascade 5: 0 XT-PIC EMU10K1 7: 81 XT-PIC HiSax 9: 387286 XT-PIC aic7xxx, aic7xxx, eth0, eth1, eth2 11: 75780 XT-PIC ide2, ide3 12: 17740 XT-PIC PS/2 Mouse 15: 2 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 To make sure I will let it stress-test overnight and send you the results in about 15 hours from now on. If everything does fine I will redo with ide2,ide3 on same interrupt, too. Just to see what happens with these Promise things... -- Thanks a lot, I'll be back, Stephan
