	Booting on Compaq ProLiant DL590/64 gets further, likely thanks to it sharing its chipset with the HP i2000. However, the kernel fails to start, displaying various errors onto the serial console, including one about ID_SALCB_GETMEDIAINFO callback error (Could not load UNDI. Status = Not Found) and several console-IO-related variables missing (ConInDev, ConOutDev, ErrOutDev, ConOut, ConIn, ErrOut).

	AIX, IBM's own flavor of UNIX, has long been relegated to a portion of IBM's own hardware, most of which has been built around the PowerPC processor architecture. However, IBM worked in combination with SCO to create a port of AIX to Intel's Itanium architecture. This page documents current known information, attempts to boot, historical context, and more combining everything we known up to this point.

	Initially, the neutral codename Project Monterey was used to refer to the system, being presented as a combination of AIX (from IBM) and UnixWare (from SCO)<ref name="montereylab" />. With the Early Adopters Release, the name was officially changed to AIX 5L for Itanium-Based Systems<ref name="relnotes" />. Variants of this are used in the documentation, including AIX 5.1 for IA-64 systems and AIX 5.1 for IA64, both being used next to AIX 5.1 for PowerPC, signifying IBM marketed them together as AIX 5L version 5.1 supporting two architectures, PowerPC and IA-64.

	Despite the marketing, there are noticable differences between the two versions of AIX. Most notably AIX/ia64 is, unlike HP-UX and AIX/ppc, little endian. Another difference is the binary format used for executables, shared libraries and the kernel: AIX/ia64 uses ELF, while AIX/ppc uses XCOFF. Both of these seem like being from SCO, matching UnixWare's ABI.		Despite the marketing, there are noticable differences between the two versions of AIX.
