I'm writing this in the Midori browser of System Rescue CD. For the sake of convenience, i'm running /etc/init.d/pxebootsrv. The box i want to boot resolutely refuses to boot from anything other than its HD. How to get it to use PXE and debug why it isn't doing so?

If the network adaptor doesn't support Pre Execution Booting you won't be able to. If you look in the BIOS and can set network as the first in the boot list you're good, if not you may have to refer to vendor documentation to determine if its supported, may require bios update.

Yes, i can do that. No sign of not being able to boot from the network. Network is first in boot order

If Network is first, might be a problem with your PXE server setup, have other clients PXE booted properly and communicated with the PXE server?

Following is a tail of /var/log/messages. Looks like Ethernet is looking OK.

It does look like it is providing an IP to the client, which is the first step, any logs on the processed you have setup that follow?

Since PXE won't work, why not try other boot options:

Try using a bootable pendrive. If that doesn't work, try another drive, another brand of drive, and another USB port.

Try another brand of CD for your Rescue CD. I have seen some systems refuse to read CDs from BrandX but work fine with BrandY.
