Hi all! Thanks again for your help getting this old Yosemite G3 B&W (PowerMac1,1) to run again. (See topic "G3 B&W powers up, but no sound and no video".)
So, System Profiler states the following: > Hardware: > > Hardware Overview: > > Machine Model: Power Macintosh G3 Series > CPU Type: PowerPC 750 (82.1) > Number Of CPUs: 1 > CPU Speed: 350 MHz > L2 Cache (per CPU): 1 MB > Memory: 512 MB > Bus Speed: 100 MHz > Boot ROM Version: 1.1.1f4 > So far so good. > PCI/AGP Cards: > > ATY,Rage128: > > Type: display > Bus: PCI > Slot: J12 > VRAM (Total): 16 MB > Vendor: ATI (0x1002) > Device ID: 0x5245 > Revision ID: 0x0000 > ROM Revision: 113-57401-116 > Working slowly, but working. > ATA: > > ATA Bus: > > Name: ATA-3 Bus > > MATSHITA CR-587: > > Model: MATSHITA CR-587 > Revision: 7S14 > Serial Number: > Drive Type: CD-ROM > Removable Media: Yes > Detachable Drive: No > Protocol: ATAPI > Unit Number: 0 > Socket Type: Internal > > ATA Bus: > > Name: pci-ata > Vendor ID: 0x1095 > Device ID: 0x0646 > Revision ID: 0x0005 > > QUANTUM FIREBALL EX12.7A: > > Capacity: 12.1 GB > Model: QUANTUM FIREBALL EX12.7A > Revision: A0A.0B00 > Serial Number: 012345678901 > Removable Media: No > Detachable Drive: No > BSD Name: disk0 > Protocol: ATA > Unit Number: 0 > Socket Type: Internal > OS9 Drivers: Yes > > Mac OS: > > Capacity: 1.97 GB > Available: 1.02 GB > Writable: Yes > File System: Journaled HFS+ > BSD Name: disk0s10 > Mount Point: /Volumes/Mac OS > > Mac OS X: > > Capacity: 9.88 GB > Available: 2.67 GB > Writable: Yes > File System: Journaled HFS+ > BSD Name: disk0s12 > Mount Point: / > The ATA-3 bus seems to be okay. The CD-ROM drive works. But why is the other bus not named ATA-4, but instead pci-ata (which is the kernel extension that is used to access it, is it not?) with cryptic IDs? Is this because I have the Revision 1 system board with the faulty IDE controller chip? > USB: > > USB Bus: > > Vendor Name: Apple Computer, Inc. > Product ID: 32773 ($8005) > Speed: Up to 12 Mb/sec > Bus Power (mA): 500 > > Hub in Apple Extended USB Keyboard: > > Vendor Name: Mitsumi Electric > Product ID: 4098 ($1002) > Speed: Up to 12 Mb/sec > Bus Power (mA): 500 > > Apple Optical USB Mouse: > > Vendor Name: Fujitsu Takamisawa Component > Speed: Up to 1.5 Mb/sec > Product ID: 770 ($302) > Bus Power (mA): 100 > > Apple Extended USB Keyboard: > > Vendor Name: Mitsumi Electric > Speed: Up to 12 Mb/sec > Product ID: 517 ($205) > Bus Power (mA): 250 > I use the keyboard and mouse from the G4 I also got. In order to get USB 2.0 I should be able to use a standard PCI extension card with a NEC USB controler chip. At least this worked for all the G4s I've got. > FireWire: > > FireWire Bus: > > Speed: 400 Mb/sec Speed > I've no use for that.

But I do notice that the system waits for a timeout or something when looking for the modem. This happens on startup of Mac OS X as well as when System Profiler shows the specs. Can I deactive it somehow, so it won't even be looking? The big issue with this Power Mac is that it will get stalled at the initial startup sequence (Open Firmware or something very early) IF I set a Startup Volume in Mac OS 9 or in Mac OS X. As I remember it this boot selection is stored somewhere in the device tree or so. In Open Firmware, typing "devalias" shows a "last-boot" entry, but it is set to "p...@80000000/pci-bri...@d/mac...@5/ethernet". Anyway, this is the only fault I could discover so far. To make the G3 fail right after switching it on, all I have to do is set the boot device in Mac OS or Mac OS X. Voila - it won't even show video. BTW, here is the whole devalias output: > Apple PowerMac1,1 1.1f4 BootROM built on 04/09/99 at 13:57:32 > Copyright 1994-1999 Apple Computer, Inc. > All Rights Reserved. > > OpenFirmware 3.1.1 > > To continue booting, type "mac-boot" and press return. > To shut down, type "shut-down" and press return. > > ok > 0 > devalias > pci /pci > bridge /pci/@d > mac-io /pci/@d/mac-io > via-cuda /pci/@d/mac-io/via-cuda > rtc /pci/@d/mac-io/via-cuda/rtc > adb-keyboard /pci/@d/mac-io/via-cuda/adb/keyboard > adb-mouse /pci/@d/mac-io/via-cuda/adb/mouse > sound /pci/@d/mac-io/davbus/sound > enet /pci/@d/mac-io/ethernet > scca /pci/@d/mac-io/escc/ch-a > sccb /pci/@d/mac-io/escc/ch-b > nvram /pci/@d/mac-io/nvram > ide0 /pci/@d/mac-io/at...@20000 > cd /pci/@d/mac-io/at...@20000/d...@0 > zip /pci/@d/mac-io/at...@20000/d...@1 > ide1 /pci/@d/pci-...@1/at...@0 > hd /pci/@d/pci-...@1/at...@0/d...@0 > ultra0 /pci/@d/pci-...@1/at...@0/d...@0 > ultra1 /pci/@d/pci-...@1/at...@0/d...@1 > usb /pci/@d/usb > firewire /pci/@d/firewire > keyboard /psuedo-hid/keyboard > mouse /psuedo-hid/mouse > usb-keyboard > usb-mouse > no-boot /p...@80000000/pci-bri...@d/mac...@5/fdc > last-boot /p...@80000000/pci-bri...@d/mac...@5/ethernet > screen /p...@80000000/ATY,rage1...@10 > ok > 0 > Anyone have an idea about this?
