Mac Os 9 booting on: xServe G4 (Detailed Posts)

<< < (2/26) > >>

MacTron:
In the xServe FW400 we have to change this properties in Open Firmware:
MacRISC3 and RackMac1,1

MacRISC3 should be changed by MacRISC2.

RackMac1,1 can be left as is, at first try. Later can be changed  it to  PowerMac3,6 (PM G4 MDD) u others models ?

Mactron... I am so interested in the results of this thread. 

Circa 2003/2004 we had 2 extra Apple Xserve G4/1.33 (Slot Load) models in our warehouse and I was going to experiment converting them into OS 9 DAW Units.

Unfortunately, we had standardized on both the 933 QS and single 1.25 MDD, so when my partner and service manager heard the fans, which get pretty loud, it was a company decision to abandon research in getting 9.2.2 and DAW apps on it; which really pissed me off.  I left the company (in New York) and moved to CA at the end of 2004 for other reasons and never got a chance to experiment with another Xserve.

interesting to see the inclusion of the "promise pdc20270"
this is the same chipset off the original "fasttrack" ide raid pci cards
which i was writing about suspecting them as the origin of the
"mac bootable" seritek firmware after reading the hex code inside the firmware file

Yes, me too... LOL

Those are just "preliminary studies" ...
An "active member" of the forum  kindly offered me a machine to test ...

So, we will see ...

I'm waiting to do the real test ...

IIO:
when i remember right, the guy where you took these pictures of the ROM hacking from never managed to come beyond the first half of the boot screen os OS9.

i would probably be much more fun to take a DDR-MDD and put it into a proper 6x19" case, right beside the PIC expansion, midi and audio IOs, ethernet switches and all this other 19" stuff.
