An alternative approach to "yelling" might be to acknowledge that you
received a response and explain that it didn't help you.

You could also try e-mailing the _gPXE_ general discussion list instead
of the _Etherboot_ list, like I gave a link for.

I'm sorry that I missed your authentication needs in your first e-mail.
Please see the attachment to this e-mail. It is a NETSH script which
demonstrates how to set up reservations that include iSCSI
authentication credentials for clients by using gPXE encapsulated
options with your Windows DHCP server.

You can edit the reservation's options manually by double-clicking the
option 175 inside the reservation, then editing the username and
password, then correcting the option length field for both username and
password.

In the attached example, both the username and password fields are 8
characters long, so you see that the field for each one has 0x08.
