Optiplex 990 iSCSI boot

Hi everyone,

can someone tell me how to enable iSCSI boot on 82579LM integrated NIC on Optiplex 990.

I tried with Intel's BOOTUTIL.EXE but it is not intended as a utility for LAN on Motherboard implementations.

According to Intel 82579LM supports iSCSI boot with Intel 6 Series Express Chipset.

Best regards,

Emir
