Since Version 2.12 of grub VMWare VSphrere VMEXNET3 Network Cards cannot get a remote configfile in Legacy(BIOS) mode.

With 2.06 it worked fine. Since 2.12 it doesn't work anymore.

Setting debug=all doesn't provide any debugging informantion.

Accessing the remote configfile is done via

configfile (tftp,IP)/PATH/grub.cfg

There is no TFTP request on the designated server. And no message on the machine itself, just a cursors and then it returns into the grub shell.

The network card however seems configured, it has the correct IP address. However running a net_nslookup doesn't return anything, same behaviours as with the configfile command.

UEFI mode works though, but some customers/users don't want to switch their VMs to UEFI.
