Location of Force_PXE_Enable token on various Dell servers

[Jordan_Hargrave at Dell.com]

Try using token 0x4022 for enabled and 4023 for disabled.

Subject: Location of Force_PXE_Enable token on various Dell servers
 
Hi,

I'm working on developing an automatic server deployment system for our
datacenter.  To that end it would be extremely handy to be able to
access the 0x0093 token (Force_PXE_Enable) which provides the following
functionality:

"The next time the BIOS boots the system, the first PXE-capable device is inserted as
the first device in the boot sequence.  Enabling this value causes this
operation on the next boot only, and does not cause a change in the
system's defined boot sequence.  The BIOS chooses the first PXE-capable
device as the system's onboard network controller, if present and
enabled, or the first bootable network device found in the system's
standard PCI search order â?" whichever comes first."

But, I've found that this only works on certain types of Dell Hardware.
Is it possible that this particular token was moved to another location
on certain hardware and if so, do you happen to know where, or how I can
find out?

Cheers,

-Jay

Problem reading or writing tag. Common problems are:
    -- Password-protection in the BIOS.
       Try using the '--password' option to specify the BIOS setup password.

    -- Insufficient permissions to perform operation.
       Try running as a more privileged account.
          Linux  : run as 'root' user
          Windows: run as 'administrator' user

    -- dcdbas device driver not loaded.
       Try loading the dcdbas driver
          Linux  : insmod dcdbas
          Windows: dcdbas driver not yet available.

(the dcdbas driver is statically compiled in, and querying other memory
locations is working fine).
