so last night i got arc firmware initial bringup the PMU is slightly different between the pre-pci and pci powerbooks, and the screen brightness/contrast pmu commands did something quite unwanted on the 1400cs, see pictures for more info. it's not a monochrome thing as colours did indeed kinda show up when booting into mac os things to do: - fix media bay, which not even linux on PBX support. media bay id and power goes through the PMU on these systems (the tbxi rom keeps reading the media bay id until two reads in a row gets the same value). i think there's only one set of ide registers on Baboon (unlike what the linux port says), need to reverse the tbxi rom more (i saw some code relating to setting some register bits to swap between the two ide controllers?). i did find out that baboon has three interrupts, two for each ide channel probably? and another for media bay insert/remove. - write scsi drivers. PBX uses an NCR 5380, PDM and cordyceps use an NCR 53c9x, so common scsi controllers
