Machine
|
|
=======
|
|
|
|
The *Machine* page contains settings related to the emulated machine as a whole, such as the machine type, CPU type and amount of memory.
|
|
|
|
Machine type / Machine
|
|
----------------------
|
|
|
|
Machine/motherboard to emulate. The *Machine type* box lists all available processor classes, while the *Machine* box lists all available machines of the selected processor class.
|
|
|
|
The *Configure* button opens a new window with settings specific to the machine's onboard devices, such as the amount of installed video memory for an onboard video chip.
|
|
|
|
CPU type / CPU
|
|
--------------
|
|
|
|
Main processor to emulate. Only processors supported by the selected machine will be listed.
|
|
|
|
FPU
|
|
---
|
|
|
|
Math co-processor to emulate. This box will not be enabled if a processor with an integrated math co-processor is selected.
|
|
|
|
Wait states
|
|
-----------
|
|
|
|
Number of memory wait states. This box is only enabled and relevant if a 286- or 386-class CPU is selected.
|
|
|
|
Memory
|
|
------
|
|
|
|
Amount of RAM to give the emulated machine. The minimum and maximum allowed amounts of RAM will vary depending on the selected machine.
|
|
|
|
Dynamic Recompiler
|
|
------------------
|
|
|
|
Enable the dynamic recompiler, which provides faster but less accurate CPU emulation. The recompiler is available as an option for 486-class processors, and is mandatory starting with the Pentium.
|
|
|
|
Time synchronization
|
|
--------------------
|
|
|
|
Time synchronization automatically copies your host system's date and time settings over to the emulated machine's hardware real-time clock. Synchronization is performed every time the emulated machine's operating system reads the hardware clock to calibrate its own internal clock, which usually happens once on every boot.
|
|
|
|
* **Disabled:** do not perform time synchronization.
|
|
* **Enabled (local time):** synchronize the time in your host system's configured timezone. Use this option when emulating an operating system which stores local time in the hardware clock, such as DOS or Windows.
|
|
* **Enabled (UTC):** synchronize the time in Coordinated Universal Time (UTC). Use this option when emulating an operating system which stores UTC time in the hardware clock, such as Linux.
