USB Legacy Mode This function, when enabled, lets you use a USB keyboard in a DOS environment. Set this to Disabled to deactivate the USB keyboard function in DOS. Onboard Ethernet Chip This parameter lets you enable or disable the LAN function on board. When enabled, it activates the LAN of the system. When disabled, it also deactivates the function. The default setting is Enabled. SMBUS Interrupt (IRQ9) The System Management Bus (SMBus) is used to control and obtain information from devices on a motherboard. It was designed for hybrid devices based on analog semiconductor technologies and with limited digital capabilities. Enabling this feature will reserve IRQ9 for SMBUS use. The default setting is Disabled . 3-28 Altos 1100E Series User's Guide 3. 7. 2 PnP/PCI System Configuration The PnP/PCI System Configuration allows you to specify the settings for your PCI devices.

If you use plug-and-play (PnP) devices, set this parameter to Auto. The system then automatically assigns IRQs to PnP devices. If your PCI device is not a PnP, you can manually assign the interrupt for each device. Refer to your PCI card manual for more information. The default setting is Auto. When the PCI IRQ Setting is set to Auto, all the IRQ setting fields become gray and nonconfigurable. PCI Slots These parameters allow you to specify the appropriate interrupt for each of the PCI devices. You can assign IRQ3, IRQ4, IRQ5, IRQ7, IRQ9, IRQ10, IRQ11, IRQ12, IRQ14, or IRQ15 to the slots. Make sure that the interrupt you assign to the various PCI slots are not used by other devices to avoid conflicts. [. . . ] Be sure that the SCSI drive to be used as drive D is set to SCSI ID 0. Check the drive manual for information on setting the SCSI ID for that device. You can also use the SCSISelect utility to determine the SCSI addresses of peripherals on the SCSI bus. Altos 1100E Series User's Guide · · · Be sure that SCSI parity checking is consistently enabled or disabled on all devices on the SCSI bus. Verify that the SCSI controller and the SCSI devices are properly configured and installed. [. . . ]
