## Appendix A - Device Summary
## Appendix A - Pre-built ROM Images
The standard ROM images will detect and install support for certain
devices and peripherals that are on-board or frequently used with
each platform as documented below. If the device or peripheral is
not detected at boot, the ROM will simply bypass support
appropriately.
#### SBC (SBC_std.rom)
- CPU speed is detected at startup
- Console on onboard UART serial port at 38400 baud
- Includes support for PPIDE/CF Card(s) connected to on-board
parallel port.
- Includes support for CVDU and VGA3 boards. If detected at
startup, support for video and keyboard is installed
including VT-100/ANSI terminal emulation.
- Auto detects DiskIO v3 floppy disk controller and installs
support for two attached 3.5" floppy disks if found
- Auto-detects PropIO or PropIO V2 and installs associated
video, keyboard and SD Card support if present.
- If PropIO, PropIO V2, CVDU, or VGA hardware is detected,
initial console output is determined by JP2. If JP2 is
shorted, console will go to on-board serial port, if JP2
is open, console will go to the detected video and keyboard
ports.
- SBC V1 has a known race condition in the bank switching
circuit which is likely to cause system instability. SBC
V2 does not have this issue.
#### SBC (SBC_simh.rom)
- SBC variant customized to run under SimH
- Implments two emulated SimH hard disk images
- Uses SimH RTC
#### ZETA (ZETA_std.rom)
- CPU speed is detected at startup

- Auto-detects FDC and installs 3.5" disk support
if found
- Auto detects on-board floppy disk controller and installs
support for one attached 3.5" floppy disk if found
- Auto-detects ParPortProp and includes support for it if it
is attached.
- If ParPortProp is installed, initial console output is
determined by JP1. If JP1 is shorted, console will go to
on-board serial port, if JP1 is open, console will go to
ParPortProp video and keyboard ports.
#### ZETA2 (ZETA2_std.rom)
- CPU speed is detected at startup
- Console on onboard UART serial port at 38400 baud
- Auto detects on-board floppy disk controller and installs
support for one attached 3.5" floppy disk if found
- Auto-detects ParPortProp and includes support for it if it
is attached.
- Uses CTC to generate periodic timer interrupts.
- If ParPortProp is installed, initial console output is
determined by JP1. If JP1 is shorted, console will go to
on-board serial port, if JP1 is open, console will go to
ParPortProp video and keyboard ports.
#### N8 (N8_std.rom)
- CPU speed is detected at startup
- Console on Z180 onboard primary ASCI serial port at 38400 baud
- Auto detects onboard floppy disk controller and installs
support for two attached 3.5" floppy disks if found
- Includes support for on-board TMS9918 video and keyboard
including VT-100/ANSI terminal emulation.
- Includes support for on-board SD Card as hard disk and
assumes a production level N8 board (date code >= 2312).
#### MK4 (MK4_std.rom)
- CPU speed is detected at startup
- Console on Z180 onboard primary ASCI serial port at 38400 baud
- Includes support for on-board IDE port (CF Card via adapter).
- Includes support for on-board SD Card port.
- Auto detects Dual IDE floppy disk controller and installs
support for two attached 3.5" floppy disks if found
- Auto-detects PropIO or PropIO V2 and installs associated
video, keyboard and SD Card support if present.
- Includes support for CVDU and VGA3 boards. If detected at
startup, support for video and keyboard is installed
including VT-100/ANSI terminal emulation.

enabled, will auto-detect and install associated
video, keyboard and SD Card support if present.
#### RCZ280 (RCZ280_ext.rom, RCZ280_nat.rom, RCZ280_nat_zz.rom)

which has both CPU and memory onboard.
- Support for PropIO V2 may be enabled in config (PRPENABLE). If
enabled, will auto-detect and install associated
