What do you mean by highlighting spans? It will highlight a length of bytes that is the size of the item selected in the template.

I'm working on a modification to extract UnivTables. Does Hex Fiend have an option to export the parsed template info as text like Resorcerer does?

The 5200 does not support Open Firmware. According to the output produced by the tbxi command, these ROMs which have a Configfile-1 file in the output do not have Open Firmware: PowerBook 1400 series ROMs/117+133/341S0203-4.rom PowerBook 1400 series ROMs/166/341S0364-5.rom Power Macintosh...

Get a ROM dump for each logic board. The color is probably stored in NVRAM somewhere. https://forums.macrumors.com/threads/question-how-powerful-of-a-graphics-card-will-work-in-a-beige-power-macintosh-g3.2303689/post-33883037 Firmware updaters starting with 3.2.4f1 read a byte at 0xFFF04177...

Open Firmware (two words) has a Forth (text) interpreter and a Forth byte code (fcode) interpreter. Apple's Open Firmware compiles Forth and fcode to PowerPC instructions so it runs reasonably well. Even while it's interpreting, it will compile loops into a temporary area so they'll also run...

The Power Mac 6100 is also not Open Firmware but the Copland disk based Open Firmware loads on that. I don't know if it loads on non-PDM Power Macs. 5200 is Cordyceps, not PDM. Since the Copland Open Firmware is disk based, I suppose it could be modified to work on other Macs but that might be a...

Would accessing the CPU via Open Firmware offer alternate means of gathering or testing such info? Copland has a disk based version of Open Firmware for NuBus Macs. https://tinkerdifferent.com/threads/powermac-7100-and-linux-and-netbsd.4368/ /openprom@0 PROPERTIES: name...

Did you have a second display connected so that you can see the Displays preferences panel for the display that was black? Or use screen sharing? Then see what display options are available? Or use SwitchResX to view more options? Connect the monitor via HDMI adapter to modern Mac and extract...

Question about MIDI: Does the serial clock have anything to do with the timing of audio and such? I think the time it takes to send a note command is much shorter than the time it takes to play the note. Therefore, the serial output is usually idle? And the timing is done by the host using its...

Since every 8 pixels is broken, you're looking for an 8 bit data bus probably. Looks like Data Bit 0 is broken. The right side of each byte is stuck black. The left side of each byte is Data Bit 7. I compared your image to an image taken from infinitemac.org with bad disk - assuming your Mac...

Cool. One day I want to work on an XHCI or NVMe driver for PPC Mac OS X. Has anyone tried XHCI or NVMe on a Quad G5 with Linux?

Well, anything > 500 MB/s is definitely at least in the PCIe gen 1 x4 range. It would be nice to know if it's possible to get into the PCIe gen 1 x8 rage (>1000 MB/s). 515 MB/s is without RAID. 645 MB/s is with RAID. That's 322 MB/s per disk. That's 60% of the single disk performance. The drop...

The Quad G5 Developer Note says the HyperTransport bus to the Mid Bridge that hosts the x4 and x8 slots is only 1600 Mb/s https://leopard-adc.pepas.com/documentation/Hardware/Conceptual/PowerMac_G5_05Oct/Articles/PwrMacG5-0510_archi.html#//apple_ref/doc/uid/TP40003917 1600 Mb/s is only 200 MB/s...

I didn't realize I volunteered. I am thinking the code path for PDM Macs (6100, etc.) probably involves the stuff I mentioned at: https://68kmla.org/bb/index.php?threads/skipping-the-startup-memory-test.50699/post-571099 I checked the Memory control panel in DingusPPC. All the options are...

The Power Macintosh 6100 emulation at infinitymac.org (uses DingusPPC) doesn't seem to have a memory test option in the Memory control panel of Mac OS 8.0 but does have the option in Mac OS 8.6. I would add some NVRAM logging to DingusPPC to see if it's accessing XPRAM or something.

In Mac OS 9, you can bless the System Folder by moving the System or Finder out and into the System Folder. A blessed System Folder will have a Happy Mac icon. My dumpvols.sh script will show which folders are blessed on each volume. It uses the bless command. It also parses the FinderInfo in...

Check devalias to see if there's an alias that you can replace /pci@f2000000/mac-io@17/ata-4@1f000 with. You usually don't need both the name (before @) and the unit address (after @) unless there's multiple nodes with the same name. So these should also work: /pci/mac-io/ata-4 /pci/@17/ata-4...

7100 and other PDM machines don't have the same NVRAM as CHRP machines. The test of the CHRPNess bit fails, so it won't do the NVRAM write for GrandCentral, OHare, or Heathrow which don't exist in the PDM machine...

UniversalTables.a shows how the bits are setup for different machines. Just need an algorithm to find this in the ROM. Edited my previous post above.
