Configuring the BIOS on the CEPC

To successfully configure a CEPC to download an OS image, you must correctly configure the CEPC BIOS and verify that there are no device conflicts. If two devices share the same interrupt request (IRQ), you cannot use both of these devices at the same time unless the drivers support interrupt sharing, which enables multiple devices to use the same interrupt.

Note   Because the download and kernel independent transport layer (KITL) Ethernet driver does not always support interrupt sharing, be sure that the Ethernet device has its own IRQ.

Consult the CEPC motherboard documentation or the CEPC motherboard manufacturer's Web site for information on entering and configuring the BIOS. Typically, you can enter the BIOS by pressing a certain keyboard key or key combination after you reboot the CEPC. Sometimes the BIOS shows you which key or key combination to use. If the BIOS does not show you the key or key combination, try pressing DELETE, function keys, or ALT in conjunction with DELETE or any of the function keys.

To configure a BIOS on the CEPC

1. Disable Plug and Play.

2. Verify that there are no device interrupt conflicts in the BIOS.

   Usually, the BIOS displays the IRQs that various devices use, typically PCI devices.

3. If, by default, the BIOS assigns the same interrupt to two devices, and these devices should not be sharing that interrupt, separate the interrupts by reserving the conflicting interrupt as a legacy ISA interrupt.
