CommandEnvSize
(#,0-32768,) Specifies the size of the COMMAND.COM environment. Specify 0 to disable, or a value between 160 and 32768. PIF settings will override this setting.

COMBoostTime
(#,,2) Number of milliseconds to allow a virtual machine to process a COM interrupt.

FileSysChange
(B,on-off,on) On will slow down performance, since File Manager has to be notified when a non-windows app creates, deletes or renames a file. Default is off for standard more, on for 386enh.
HardDiskDMABuffer
(#,,) Number of kilobytes used for DMA buffer. Default is 0 for AT machines, 64 for MCA and machines using DMA 3, unless SMARTDRV double buffering is used, then 0.
IgnoreInstalledEMM

InDOSPolling
(B,on-off,off) When on, prevents windows from running other applications when TSR software has the InDOS flag set. On will slow down performance slightly.
INT28Critical
(B,on-off,on) Specifies whether a critical section is needed to handle INT 28h interrupts by TSR software. Off may improve task switching.
IRQ9Global
(B,on-off,off) Set to on to make IRQ9 masks global, or if your system hangs when accessing the floppy drive.

MaxComPort
(#,,4) Specifies the maximum number of COM ports supported in 386 enhanced mode.
MaxPagingFileSize
(#,,) Sets maximum size of the temporary swap file. Default is 50% of available disk space. Can also be changed thru 386 Enhanced icon in Control Panel.
MaxPhysPage
(S,,) Maximum physical page number that the VMM can use. This is useful since some ISA DMA network cards can't address beyond 16MB, so you would reduce this number.
MCADMA
(B,on-off,off) On will allow windows to use Micro Channel Architecture DMA extensions. Default is on for MCA machines.
MessageBackColor
(#,1-16,1) Specifies the background color of message screens, like the one when you press CTRL+ALT+DELETE. Entry is a VGA color attribute.
MessageTextColor
(#,1-16,1) Specifies the foreground color of message screens, like the one when you press CTRL+ALT+DELETE. Entry is a VGA color attribute.
MinTimeSlice
(#,,20) Minimum number of milliseconds a virtual machine can run before switching to another virtual machine. Lowering this value makes multi-tasking appear smoother, but degrades performance. Also change thru 386Enhanced icon in Control Panel.
MinUserDiskSpace
(#,,500) Specifies the number of kilobytes to leave free on your hard disk when windows creates a temporary swap file.
MouseSoftInit
(B,on-off,on) On will convert hard mouse init calls to soft ones. Set to off if cursor and screen appear distorted, which will also prevents using the mouse in non-windows apps in a window.
NoEMMDriver

Paging
(B,on-off,on) On permits the use of a temporary swap file.
PagingDrive
(S,,) Disk drive where windows will allocate a temporary swap file. Ignored if using a permanent swap file.
PagingFile

SysVMXMSRequired
(#,,0) How much extended memory must be free to start windows.

UseableHighArea
(S,A000-EFFF,) Hex paragraph range windows will scan for free memory. Takes precedence over ReservedHighArea.
UseROMFont
(B,on-off,on) When on, windows uses the font in video ROM for messages in non-windows apps. Set to off if font is wrong or garbage appears on screen.
VGAMonoText
(B,on-off,on) When off, windows ignores the monochrome address space, making the B000-B7FF range available in upper memory if a hardware device isn't using it.
VirtualHDIrq
(B,on-off,on) On allows windows in 386 enhanced mode to terminate interrupts from the hard disk controller, speeding disk access. Some drives need this set to off.
