My fork lets you enter more than one --hdd_img parameter so you can use : for drive letters in Windows. My fork also has the ability to specify device paths with SCSI or ATA ID numbers so you can place the HD exactly where you want. My fork adds --hdd_part which lets you catenate partitions from...

I think there should be a "waiting on" message near the beginning that indicates the expected I/O Registry path that it is waiting for. It should be the same disk you are booting from. What disk are you booting from? The message comes from xnu/iokit/bsddev/IOKitBSDInit.cpp using "IOLog". There...

What does it think is the root device? If you're booting from an ISO that is burned to a DVD, then the root device should be a partition on the DVD drive. A root device may work from EFI and be able to load the boot loader (as you are experiencing). The boot loader then loads the kernel and OS...

The first problem is a vertical white line, then 6 or 7 or 8 vertical black lines, every 16 pixels. If the problem was a broken trace, then the lines would all be the same color (usually black) and appear across the full width of the display. The lines appear at the left edge of the display. Is...

True. DingusPPC has hardware cursor emulation for ATI graphics cards, and built-in graphics controllers (control and platinum) used by Power Macs. sixty6 doesn't use a hardware cursor. Other graphics controllers aren't implemented yet.

The ERS and cuda firmware source code were posted at https://68kmla.org/bb/threads/getting-rid-of-the-your-clock-is-not-set-to-the-correct-time-alert-dialog-after-system-7-boots.45952/post-511487

This video by Action Retro shows removing and replacing the speaker fabric: I suppose it is too difficult to remove and reuse the old fabric?

I think I have a binary that can do Gazelle machines (PSX based) but I don't know if it works or is complete. At least, the code may possibly show how to enable flashing of a ROM SIMM that is installed and working in a Gazelle machine. Flashers (stored as XCOF resources in the Flasher...

Probably not. You probably have to make your own or use a different flashing method. Do you know if it's 5V or 3.3V? Is it 4 MiB? Since it only has 4 chips, it's probably not programmable by Apple's Flasher utility without creating your own flashing code. Apple's Flasher utility is useful only...

That's what I thought. I put the details in DingusPPC source code even though it can't run most of the ROMs. At least it can identify them. https://github.com/joevt/dingusppc/blob/master/machines/romidentity.cpp The 1 MB New World ROMs are interesting. The machine is identified by the product...

Not sure what "real hardware risu data" has to do with a list of ROMs.

The subversion column is not applicable to some earlier ROMs. The table is missing additional checksums. The shown checksums of 4 MB ROMs only cover the first 3 MB. The attached excludes the subversion from where it doesn't apply. It also includes all the other checksums. For the 3 MB part...

That works on my Quad G5 (running with 3 CPU cores) with 7800 GT Mac Edition (currently using my 64K compressed ROM). Currently using a display set to 2560x1440. - 9331 in Leopard 10.5.8 - 12700 in Leopard 10.5.8 after putting the display to sleep for a second by moving the mouse to a hot...

The ANS code has one fcode image for the GD5430. I would have just used that to create an fcode image for a PCI Option ROM but some additions/changes would be needed to handle words that are in the ANS ROM but not part of the Open Firmware spec. Your ROM is currently set to compile for GD5446...

The post at https://68kmla.org/bb/threads/refurbished-powermac-6500-acting-up-did-i-do-it.50456/post-570219 says if it finds an IDE drive, it will try to boot from it but if the OS is not a supported version then it will not try SCSI drives. I don't know if it would look for a SCSI drive on a...

Makes sense. UE8 has an 8 bit bus. Bit 4 is VID(4) which is pin 10 on UE8 and pin 2 on UC6.

If that's a black and white 1 bit graphics mode, then there's a problem with an 8-bit bus so ignore any buses or chips that are 16 or 32 bits. It looks like a problem with the 4th pixel from the left. That is bit 4 (bit 0 is the 8th pixel) for 8-bit buses. Bit 12 and 4 for 16-bit buses. Bit 28...

Which systems are you referring to? What ROM checksum?

A user of a rev C ROM Beige G3 reports that applying the cache line size and master latency timer fix that exists in the rev D ROM for PCI bridges improves performance. You can test this on a Beige G3 or any Power Mac. First, find the config address of the PCI bridge that contains the...
