#Intel: Shouldn't we just extend x86 into 64-bit?

Also Intel: No, let us waste $Billions restarting from scratch.
Nothing can possibly go wrong.

Today, we point and laugh at #Itanium:

Itanium: Intel’s Great Successor

YouTube

@benjojo There’s an IPMI brute-force around, if that's not what you're doing here.

CVE-2013-4786

https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c04197764

This is reportedly unfixable on various HP servers.

“HPSBHF02981 rev.4 - HPE Integrated Lights-Out 2, 3, 4, 5 (iLO 2, iLO 3, iLO 4, and iLO 5) and HPE Superdome Flex RMC - IPMI 2.0 RCMP+ Authentication Remote Password Hash Vulnerability (RAKP)”

TL;DR: ask nicely for a weakly-hashed IPMI password, then crack it offline.

On at least some of these boxes, the iLO command that blocks this access:

since this has never been mentioned outside of 370network, here is something funny we (@morc) did in like the first few days of 2026 #itanium #ia64 #totalx86death

I didn't realize that x86_64 went back that far. I'm guessing it was AMD-only at the time, as Intel was still thinking that #Itanium hung the moon. XD
