I really enjoyed (and still) Open Firmware which was used by Apple on the PowerPC macintosh (starting from the first PCI models up to the latest G5)
It is a nice environment, with all the capabilities of UEFI with even more as it come for free and directly with a Forth interpreter (basically the CLI is an immediate forth interpreter) Was quite nice and tidy, allowing lots of stuff like modifications of the device tree and other nice things. Was probably underused by Apple but yet, was the key for a lot of hacks on PPC models! I think it was originated from Sun and use on spark station, not really sure there > Le 31 août 2018 à 18:19, Andrew Lowe <a...@wht.com.au> a écrit : > >> On 31/08/18 23:16, Andrew Udvare wrote: >>> On 8/31/18 10:46 AM, Andrew Lowe wrote: >>> Hi all, >> >>> This is not to start a flame war, I just want to do some reading, >>> wikipedia pages, for self interest on how a BIOS could have/should have >>> been done.
