Hello everyone, I'm writing this application for UEFI using the UDK and in it I'm trying to gather some information from the SMBios table.
I'm trying to reach the System Event Log, and in order to do that I've decoded the System Event Log(Type 15) structure and found that, in my machine, the field "Access Method" has a value of '4', which, according to the SMBios spec, means "Available through General-Purpose NonVolatile Data functions." I have little to no idea of what "General-Purpose NonVolatile Data functions" are. I've looked into the Linux kernel source only to find that it explicitly does not support such access method, so I cannot use that as a reference. The only other reference to the term 'gpnv' that I could find was in an old SMBios spec, which references something called "Plug and Play functions", which I also am not familiar with. I'd appreciate any help regarding these questions: 1 - What are "General-Purpose NonVolatile Data functions"? 2 - How do I use them? 3 - Is there any UDK api to handle them? Thank you very much. Tomaz
