Hello All,
I am posting this in several groups to hopefully get more attention.
I am far from being a programmer but I have a pretty technical mind and have
uncovered a compatibility issue that I have submitted to Apple technical
support. I actually got past the first level technicians to talk to a
support specialist that agrees with me on my diagnoses. Unfortunately, I
don’t know how to proceed and I fully expect Apple engineering (yes, he said
he would actually submit my issue to the engineering department) to reply in
a couple of days saying they wont support me with my configuration.
I will try to be brief in describing the actual problem. I have a Power
Macintosh G3 266 MT revision a. I put a Apple OEM 2940u2b scsi card in and
it works perfectly with OS 9.x and previous. It refuses to boot OS X even
though OS X installer allows the install and works perfectly. I done many
things to prove that it is the card and not the drive and other hardware and
so on but I don’t want to bore you with details. The hard disk boots fine
after an install when you move it to the internal SCSI.
This card originally shipped with B&W G3′s and works fine on those machines.
They have open firmware 3.x & above. This Mac has version 2.0f1 and is not
flash-able. That’s where the nvram comes in. I can see the device in OF when
doing a "dev / ls" command. When I try to do a DIR listing that’s when I get
an error message. Here is the message: "can’t open disk label package, can’t
OPEN the DIR device, OK" I haven’t tried yet, but I’m betting it all that no
other OS will boot because of this.
Now, this card is compatible with B&W OF 3.0. There has got to be a way to
put commands in the OF to mock the v3 OF so that we can access the DIR on
the HD attached to the SCSI card. Both the card and the disk have the word
"open" available when you ask it for its words.
ANY HELP OR IDEAS HERE WOULD BE GREATLY APPRECIATED!
Thanks,
Jeff Kazules
