Yes. The spec does not allow you to write to the iBFT - only read. The BIOS (or the firmware on the NIC, or your PXE boot loader - gPXE) generates these structures during boot. > > Can't dynamically changing parameters like target ip-addreseses, iqns > and others etc. be configurable through userspace via sysfs? Can't do. Well if you are using the IBM blades, they do have a Java tool (Blade Configuration something) that allows you to set those entries and on bootup the BIOS would generate them. The mechanism it uses to write that data is completly vendor-specific however. > > I think we do have precedence of firmware parameters being modified > using sysfs. Yes.
