Matrox 4Sight-II Installation And Hardware Reference page 117

• Legacy USB Support:
This item allows you to enable or disable the USB ports. Disabling the USB ports
makes it impossible to connect a USB device (such as a keyboard) to your unit.
Options:
- Disabled
- Enabled (default)
• Local Bus IDE adapter:
This item allows you to enable or disable the primary and secondary ATA-44
interface. The primary ATA-44 interface uses IRQ14, and the secondary ATA-44
interface uses IRQ15. If, however, one of these IRQs is required for another device,
you can disable an ATA-44 interface, and free up an IRQ line.
By selecting Disabled, both ATA-44 interfaces will be disabled, making IRQ14
and IRQ15 available. By selecting Primary, only the primary ATA-44 interface
will be enabled, making IRQ15 available. By selecting Secondary, only the
secondary ATA-44 interface will be enabled, making IRQ14 available. By selecting
Both, the primary and secondary ATA-44 interfaces will be enabled, so neither
IRQ14 nor IRQ15 will be available.
Options:
- Disabled
- Primary
- Secondary
- Both (default)
