Re: [Freeipmi-users] Can I deduce sensors meaning from record ID?

No, the record IDs cannot be assumed to be the same on all possible machines.

However, it is common to use record IDs to program per all identical
motherboards (i.e.
Vendor Model X motherboard) with identical firmware versions.  The
record IDs on all
identical motherboards should be the same.

Hope that helps,
