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 machine classes, while the *Machine* box lists all available machines on the selected 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 to use on a 286- or 386-class processor. This box will not be enabled if any other processor family 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 guest 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.
