Can you reset BIOS settings to optimized defaults on all 3 boards? As a way to eliminate BIOS settings differences.

After the upgrade, I made the necessary changes to the pxelinux.cfg file to add the new kernel. Now only 2 of the 3 machines boot. The other machine will not boot using the new kernel, only the old one. When I select the new kernel, it tftps the kernel and initrd (I see two "Loading..." lines printed to the screen, also verified in the tftpd logs). Then it just hangs, and doesn't print a single kernel message. All the motherboards have the latest BIOS and have the Intel Boot Agent that they shipped with (doesn't appear to be upgradable). I really have no idea what else to try. Any ideas on how to debug this? _______________________________________________ Syslinux mailing list Submissions to Syslinux at zytor.com Unsubscribe or set options at: http://www.zytor.com/mailman/listinfo/syslinux

Any ideas on how to debug this?If, after reset, the issue persists with the one, a more detailed problem statement is in order, including PXELINUX version (and where it comes from), add-in cards, and RAM. Although you're unlikely to be hitting a minor hardware fault, another step to try might be to consider swapping RAM. -- -Gene
