Not Linux related but maybe you guys know what function BBh of Int 0x1A on a
PC is related to (which spec covers it)?

Thanks.

I don't see a function BB Int 1A in Ralf Brown's list. Where did you find it?
Do you mean 88 or 8B? Those are PCMCIA BIOS functions.

No, BBh - used by Win7 boot up.

I've found that it has something to do with TCPA but still haven't found the
spec that documents the int 1a function bbh yet.

This is the hook to the various TCG functions such as
TCG_PassThroughToTPM, TCP_StatusCheck, and so on.
