PXE boot with Realtek 8111B/C
Having got FOG running I was over the moon. Our new batch of 25 Tosh laptops went in about as painlessly as possible. So, let's now turn to the 30-odd new Akhter all-in-ones ....
I simply cannot get them to PXE boot. They have the same network adaptor as the Toshes, Realtek 8168/8111, but always fail to find a DHCP or DHCPproxy request.
I tried a etherboot CD, first on one of our NS Optimum PCs (which have the same adaptor) then on an Akhter. The NS Optimum (which was also refusing to PXE boot) worked fine with this CD - but the Akhter won't.
Oddly, the NS Optimum will now PXE boot happily without the CD. It seems that changing the boot device order from LAN/HDD/CD to CD/LAN/HDD was enough to persuade it to work, so that sounds like a timing issue. We are running spanning tree protocol and that is supposed to cause PXE boot problems.
But it works fine on the Toshes, and on other, older, machines around the campus. Any ideas? All straws gratefully clutched at.
