Hi, Looking good so far. It can do the following: - get the correct mac address - show the correct link speed - identify it as a PCI express adapter - get an ip address
Not working yet though. Here is the screen output: Tigon3 [partno(none) rev a002 PHY(unknown)] (PCIX:100MHz:32-bit) Link is up at 1000 Mbps, full duplex. WARNING: Using legacy NIC wrapper on 00:1c:23:26:82:e7 gPXE 1.0.1 -- Open Source Boot Firmware -- http://etherboot.org Features: AoE HTTP iSCSI DNS TFTP bzImage COMBOOT ELF Multiboot PXE PXEXT DHCP (net0 00:1c:23:26:82:e7)... ok tftp://server.net/file.gpxe./menu.c32..transmit timed out tg3_stop_block timed out, ofs=0x4c00 enable_bit=002 Firmware will not restart magic=0x4b657654 Firmware will not restart magic=0x4b657654 and so on.... I will try and look at the linux kernel sources of tg3.c and see if I can find more info on the 5755. Any other ideas would be helpful.
