4. BIOS SETUP
PS/2 Mouse Function Control [Auto]
The default of [Auto] allows the system to detect a PS/2 mouse on startup. If detected, IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards only if a PS/2 mouse is not detected. [Enabled] will always reserve IRQ12, whether on startup a PS/2 mouse is detected or not. Configuration options: [Enabled] [Auto]
OS/2 Onboard Memory > 64M [Disabled]
When using OS/2 operating systems with installed DRAM of greater than 64MB, you need to set this option to [Enabled]; otherwise, leave this on [Disabled]. Configuration options: [Disabled] [Enabled]
USB Legacy Support [Auto]
This motherboard supports Universal Serial Bus (USB) devices. The default setting [Auto] allows the system to detect a USB keyboard at startup. If detected, the USB controller legacy mode is enabled. If not detected, the USB controller legacy mode is disabled.
When you set this field to [Disabled], the USB controller legacy mode is disabled whether or not you are using a USB device. Configuration options: [Disabled] [Enabled] [Auto]
