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 ?
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.
"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.
