Cannot flash Intel nic: "invalid image file"

[jgarr]

I give up. I'm guessing there's a limitation on my nic because even trying to flash an official updated rom (flb) file extracted from preboot utility I get

"Option ROM area in the flash is not supported for this device on port 1"

I also tried a -RESTOREIMAGE and get

"ERROR: Failed processing FLB file for port 1"

Wondering if this is a limitation because I'm using HP hardware.
