Description
Use this setting to select whether the operating system is compatible with Plug and Play (PnP).
The default setting is Yes. Always use the default setting.
Use this setting to reset the PnP information recorded in the Extended System Configuration
Data (ESCD) block when restarting the system.
The default setting is Disabled. Always use the default setting.
Use this setting to select whether the allocation of the I/O address, IRQ, DMA, and other system
resources is to be done by PnP BIOS or by the user.
The default setting is Auto (ESCD). Always use the default setting.
Sets the handling of IRQ Resources (interrupt number).
You can change IRQ Resources 3, 4, 5, 7, 9, 10, 11, 12, 14, and 15.
The default setting is PCI/ISA PnP for each resource.
PCI/ISA PnP: The target IRQ resources are allocated automatically (dynamic allocation)
by PnP BIOS, as is the case when the Resource Controlled By setting is set to
Auto (ESCD).
Legacy ISA: The target IRQ resources are reserved (static allocation) and are not
affected by the PnP BIOS automatic (dynamic) allocation. When making
changes, be careful not to create a resource conflict.
Sets the handling of DMA resources (DMA channels).
You can change DMA Resources 0, 1, 3, 5, 6, and 7.
The default setting is PCI/ISA PnP for each resource.
PCI/ISA PnP: The target DMA resources are allocated automatically (dynamic allocation)
by PnP BIOS, as is the case when the Resource Controlled By setting is set to
Auto (ESCD).
Legacy ISA: The target IRQ resources are reserved (static allocation) and are not
affected by the PnP BIOS automatic (dynamic) allocation. When making
changes, be careful not to create a resource conflict.
Use this setting to position the Upper Memory Block (UMB) in the expansion memory range.
Reserved Memory Base
Sets the position address. The default setting is N/A, indicating that no position is selected.
The only position address that can be selected is D000.
Reserved Memory Length
If a position address is set, select the memory size for that address.
The default setting is 64K. The only memory size that can be selected is 64K, the same as the
default setting.
When a video card is added or when using an MPEG playback card at the same time, the on-
screen color may not display correctly for a period of time.
If this occurs, you may be able to fix the problem by changing the setting to Enabled.
The default setting is Disabled.
