We then tried using etherboot with a mknbi tagged image and also had the same results. Since we are getting the same problem on 3 different motherboards with 2 different network adapters, I have not looked into updating the boot rom on the nics. Should I? What should I look into next? I have attached a serial console log of the system and errors. The slashes and pipes you see are from a spinning bar thing. If you want output that is cleaned up without that, I can provide it. -- Richard Warner Lead Systems Integrator Microway, Inc (508)732-5517 --MIMEStream=_0+228666_922755298866_559463914737 Content-Type: text/plain; charset="iso-8859-1"; name="new-pxelinux.txt" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="new-pxelinux.txt" Bootdata ok (command line is initrd=initrd.img.gz ramdisk_size=46080 rw root=/dev/ram0 devfs=nomount init=/restore console=tty0 console=ttyS0,115200 BOOT_IMAGE=vmlinuz ) Linux version 2.6.12-rc3-em64t-mcms (root@master.cl.usgs.gov) (gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)) #6 Thu Apr 28 10:11:16 EDT 2005 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009b400 (usable) BIOS-e820: 000000000009b400 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e4000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000007ff70000 (usable) BIOS-e820: 000000007ff70000 - 000000007ff78000 (ACPI data) BIOS-e820: 000000007ff78000 - 000000007ff80000 (ACPI NVS) BIOS-e820: 000000007ff80000 - 0000000080000000 (reserved) BIOS-e820: 00000000e0000000 - 00000000f0000000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved) BIOS-e820: 00000000ff800000 - 00000000ffc00000 (reserved) BIOS-e820: 00000000fffffc00 - 0000000100000000 (reserved) Intel MultiProcessor Specification v1.4 Virtual Wire compatibility mode.
