Hi we are trying to PXE boot but it says ---->
PXE-E61 : Media test failure , check cable PXE-M0F : Exiting Broadcom PXE ROM .
What should we check for ?
"Media test failure", as emphasized by "check cable" means that there is no link detected on the local NIC.
Do you have the link led on for this machine ? If so, you might assume a buggy PXE/bios rom. If not, make a physical fix.
I guess you're trying to netboot a netbook via Wi-Fi — forget it!
Generally, this means PXE BootLoader can use no network connection. Check your cable.
