Have yet to test the “larger HD” claims of the QS “B” boards but did test various OS installs on the 867 MHZ QS with the “A” board, hoping that some OS X install or version of OS 9 to OS 9.2.2 would somehow provide that
Firmware
Update.
No-go.In the past, have seen references to other
FU installers but now cannot locate a 4.3.3f2 version updater - BUT
have found and
updated to
other FU versions in the past (mostly for Sonnet and Newertech processor upgrades) and do remember the old Apple page listing various
FUs. [Thanks refinery… still looking for that here as well. Hope it is eventually found.]
After all the various OS test installs here last night with the original “A” board in place… and
only after finally installing a “B” board… did Firmware Version 4.3.3f2 actually make its’ appearance. I even tested with various 867 MHz processors.
Now, there is a very stable 867 MHz Quicksilver with 80 GB HD running OS 10.4 & OS 9.2.2 with an 867 processor manufactured in Singapore. (An earlier 867 processor - made in the US - was somewhat
unstable in comparison.) Large HD tests - this weekend.
Currently… while the A or B boards are not specifically referenced in the Apple System Profiler or under the Hardware Overview in OS X on the QS - it’s probably a safe bet to assume that Firmware Version 4.2.5f1 signifies an A board while a Firmware Version 4.3.3f2 would clue one that a B board is present.
part12studios: perhaps it’s best & easiest just to look on the board for that A/B I.D. You’ve already found where that’s located. And those images I posted of the “white-tagged” 800 MHz DP QS… actually that's a 1 GHz DP processor. But it is on a “B” board.
Yes IIO, there were other Quicksilver “flavors” omitted from those two comparison images, earlier copy-pasted from everymac.com.
https://everymac.com/systems/apple/powermac_g4/index-powermac-g4.html I was too lazy to provide them all.
AND that earlier image posted from Wikipedia showing the 933 with an ATA 5 controller… well it
is from Wikipedia and subject to perpetual and possible correction… but, if this 867 QS now with a “B” board (with ATA 5 controller) does recognize larger drives…?
Well, there’s
always a bit of possible trickery (and resultant confusion) to contend with, ehh?
Yup… weird.
