Hi,
The old PI spec stated pass "zero" to start finding the first
entry. The latest PI spec changed it to pass 0xFFFE. You could try to make
SmbiosHandle as 0 and see if it is good. I supposed your real platform BIOS
supported old PI spec.
SmbiosHandle
On entry, points to the previous handle of the SMBIOS record. On exit, points
to the next SMBIOS record handle. If it is zero on entry, then the first SMBIOS
record handle will be returned. If it returns zero on exit, then there are no
more SMBIOS records.

Yes. It's always breaking with status EFI_NOT_FOUND.
I've tried on others systems to be sure it's not a issue on the firmware.
Failed on all systems.
At. Pi spec we have:
"SmbiosHandle
On entry, points to the previous handle of the SMBIOS record. On exit, points
to the
next SMBIOS record handle. If it is FFFEh on entry, then the first SMBIOS record
handle will be returned. If it returns FFFEh on exit, then there are no more
SMBIOS
records."
Should work. Maybe is a stupid error.
I'll continue to try, but if you have any idea, please tell me.
Thanks and Regards.

Probably because it is your original code. My apologies I missed its
initialization as a part of declaration(your message badly formatted by
my mailer).
So what is the Status value? Is it EFI_NOT_FOUND?
