IBM PC Device Configurations
IBM PC Machine Configurations are built from a collection of devices, including:
- CPU
- RAM
- ROMs
- Keyboards
- Video Adapters
- Floppy Disk Controllers
- Hard Disk (Fixed Disk) Controllers
- Control Panels
Each of those devices can be configured in multiple ways, and some support external UI controls.
For example, the IBM PC Keyboard component supports different keyboard models (eg, 83-key, 84-key, 101-key), and each of those models can also be configured to have dedicated buttons for selected key combinations, or even entire keyboard layouts.
Complete machine configurations are constructed from those devices. A machine configuration is a single XML file that lists all the device components to be used. A machine XML file can choose to configure every device itself, or it can include pre-configured device XML files, such as those provided above or elsewhere.
For example, here's what the machine located at /devices/pc/machine/5150/mda/64kb/machine.xml looks like:
<machine id="ibm5150" class="pc" border="1" pos="center" background="#FAEBD7">
<name pos="center">IBM PC (Model 5150) with Monochrome Display</name>
<computer id="pc-mda-64k" name="IBM PC" resume="1"/>
<ram id="ramLow" addr="0x00000"/>
<rom id="romBASIC" addr="0xf6000" size="0x8000" file="/devices/pc/rom/5150/basic/BASIC100.json"/>
<rom id="romBIOS" addr="0xfe000" size="0x2000" file="/devices/pc/rom/5150/bios/1981-04-24/PCBIOS-REV1.json"/>
<video ref="/devices/pc/video/ibm/mda/ibm-mda.xml"/>
<cpu id="cpu8088" model="8088" autostart="true" padleft="8px">
<control type="button" binding="run">Run</control>
<control type="button" binding="reset">Reset</control>
</cpu>
<keyboard ref="/devices/pc/keyboard/keyboard-minimal.xml"/>
<fdc ref="/disks/pc/samples.xml" pos="right"/>
<chipset id="chipset" model="5150" sw1="01000001" sw2="11110000"/>
</machine>
All the devices are fully configured within the XML file, except for the Video, Keyboard, and Floppy Disk Controller (FDC) components, which are defined in separate XML files.
