Amen bro... Sun did a nice job on that. Although the Alpha Boot ROMs were pretty good too. At least they were UNIX like and were extensible like the Sun boot ROMs. HP's were better than a PC BIOS, but they were pretty awful.
Can't say the same for UEFI, I disable that crap.
Well, it beats the crap out of IBM's BIOS, but that bar is very low. UEFI was sort of a 'camel' (a horse designed by committee) and too many people peed on it. Intel created EFI to try to fix BIOS and then people went nuts. Apple's version is the best of them, but as you say, they all suck if you have seen anything better. A big problem IMO is that EFI tried to be somewhat compatible. In the end, they were not, so you got the worst of both (new interfaces and legacy functionality).
Server systems that support IPMT have Minux under the covers in coprocessor, which using a coprocessor is also how Apple runs UEFI. With IMPT, it is sort of sad more of it is not really exposed, but you need the added cost of the coprocessor. Plus it adds a new security domain, which many people complain about. I try to know as little about it as possible to get my work done, but exposing more of that interface might help.
