The Apple Network Server HardwareDevNotes.pdf document does not say how parity is detected. Did Apple tie parity pins to the revision ID of the 53c825 or am I missing something in the ExceptionTable (startup) code?

This one shows the non-parity RAM message: "0128 Megaytes RAM" An ANS with parity RAM would show: "0128 MB Parity RAM" after doing "Testing Parity DIMMs" What's the revision of the 53c825 in this machine? Use lspci for Open Firmware to find out. #50 See here for more info: #305

According to testing done at #48 , a PCI device at device number 0x11 (usually an 53C825) connected to the first PCI bus (@F2000000) will cause the ANS startup code to perform a Testing Parity DIMMs when the revision is not 2 (pci config space register at offset 0x08). Since...

Dump the rom (DeclData) with SlotsGrab and parse the results with SlotsParse. https://github.com/joevt/SlotsDump The parsed info should list all the supported video modes. https://68kmla.org/bb/threads/calling-all-roms-collecting-declrom-data.46056/ Another option for parsing the DeclData is...

I tested built in video output of my Power Mac 8600 (vci0/control in Open Firmware). In Open Firmware, I had to load the Control3.of version of the control driver because the ROM version only supports 640x480@67 and 640x480@60VGA. I used dipswitches 13467 of the Apple to VGA adapter (same...

Power Mac 7500/7600/8500/8600 support 12" RGB. You can see info about the supported mode in the Control2.of source code file in Apple Open Source project boot-68 (APSL 1.0 era), boot-73 (APSL 1.2 era), and in the RhapsodyiOS GitHub project boot-2 directory, and Control2.c in XPostFacto. An...

I would choose 13467. Do you have a different Mac that supports 512x384 to make sure the adapter+display works? A Macintosh LC? Any Power Mac with built in video or an ATI video card?

Visit emaculation.net forums. They have threads discussing different emulators. For Mac OS 9, there are these: - qemu - SheepShaver - there's a version with 3D acceleration I haven't tried yet - a version that works with Mac OS 9.1 and later is being developed. - DingusPPC - we have a discord -...

Right. Apple System Profiler doesn't list every PCI device. Just ones in slots that have slot names. The ANS 2.0 ROM does away with the Apple Network Server slot naming and uses PowerSurge type slot names. Your problem is that the method used to attach the 54M30 driver to the device does not...

I would check the Name Registry using Display Name Registry or DisplayNameRegistry or my DumpNameRegistry to see what is visible to the OS. https://68kmla.org/bb/threads/silicon-image-sil3112-flashing-easier-way-using-flashrom.7013/post-472471...

The 66 MHz slot of B&W G3 and Yikes is weird because it's basically an overclocked slot that can't run at 33 MHz like a normal PCI slot can. So if a card works in that slot then you know for sure that it's working at 66 MHz. 32 bit PCI to PCIe bridges are obtainable. 64 bit PCI to PCIe bridge...

"Mac OS ROM" file is for New World Macs. It contains Open Firmware code which means it's loaded by Open Firmware. Once the ROM is setup, then it can load the Mac OS 9 drivers from the driver partitions of the disk just like Old World Mac ROMs do. Old World Mac ROMs are like the "Mac OS ROM"...

All the ROMs are in my fork of MacROMan. See the doonerom command in the mac_rom_checksums.sh script. It reads and verifies all checksums of a ROM. Use the script like this: source mac_rom_checksums.sh doonerom path_to_rom Results are in romlist.txt which shows how checksums changed since the...

Your solutions to the problem basically amount to avoiding the problem - either by not using LBA 48 disks to their full potential or by not using the affected IDE controllers. I was just saying that the problem (drive size limits, etc) is not hardware related but firmware or software related...

The The screen device can't be opened again? Could be a Open Firmware bug. Or it could be a bug in the graphics controller emulation. DingusPPC doesn't emulate the built-in graphics controller yet, so I can't compare. Someone with a real ANS could try it. " screen" output In the Granny Smith...
