Memory Hole At 15M-16M [Disabled] When set to [Enabled], this feature frees the PCI bus when the CPU is accessing 8-bit ISA cards. This process normally consumes about 50-60 PCI clocks without PCI delayed transaction. Set this field to [Disabled] when using ISA cards that are not PCI 2.1 compliant. Configuration options: [Enabled] [Disabled] PCI 2.1 Support [Enabled] This field enables or disables the PCI 2.1 features. Onboard PCI IDE Enable [Both] This field allows you to enable either the primary IDE channel or secondary IDE channel, or both. You can also set both channels to [Disabled]. Configuration options: [Both] [Primary] [Secondary] [Disabled] IDE Bus Master Support [Disabled] This field enables or disables each IDE channel. 2.4.2 I/O Device Configuration Floppy Disk Access Control [R/W] When set to [Read Only], this parameter protects files from being copied to floppy disks by allowing reads from, but not writes to, the floppy disk drive. The default setting [R/W] allows both reads and writes. Configuration options: [R/W] [Read Only] Onboard Serial Port 1 [3F8H/IRQ4], Port 2 [2F8H/IRQ3] These fields allow you to set the addresses for the onboard serial connectors. Serial Port 1 and Serial Port 2 must have different addresses. UART2 Use As [COM Port] This field allows you to select the device on which to assign UART2.
