# DACula
This video RAMDAC appears to be exclusive to the Power Mac 7200.
# USB
Support is only present in New World Macs, despite the presence of strings in the Power Mac G3 Beige ROM. Most Macs support 1.1, with 2.0 support present in G5 Macs.

Change where the output of OpenFirmware is directed to, either to the command line (with stdio) or a Unix socket (unavailable in Windows builds). OpenFirmware 1.x outputs here by default.
### Command Line Examples
```
dingusppc -b bootrom-6100.bin --rambank1_size 64 --rambank2_size 64 --hdd_img "System_712.dsk"
```
The user has specified their own ROM file, which is for a Power Macintosh 6100 and has also set up two separate RAM banks to use 64 MB. Note that if a second RAM bank is to be specified for the 6100, it should be the same size as the first RAM bank. With only a hard disk specified, the machine will immediately boot to the OS on the hard disk.
```
dingusppc -b "Power_Mac_G3_Beige.ROM" -r --rambank1_size 128 --fdd_img "DiskTools_8.5.img"
```
Here, the user has attached a floppy disk image. They've chosen to boot it from a G3 and the first RAM bank is set to 128 MB.
```
dingusppc -b "Power_Mac_G3_Beige.ROM" -d --rambank1_size 64 --rambank2_size 64 --cdr_img "OpenDarwin_662.cdr"
```
The debugger will be turned on here, due to the presence of `-d`. The CD ROM image will be loaded in.
## Accessing OpenFirmware
After booting from a PCI Power Mac ROM without any disk images, enter the debugger and change the NVRAM property `auto-boot?` to false. Quit of the emulator and boot it back up to access it.
