Chapter 3 BIOS Setup IRQ Assignment Table There are 15 interrupt sources of the system. Some are occupied by the system devices. Only the ones that are not occupied can be distributed. The ISA devices claim to engross the interrupt. Only the plug and play ISA devices can be distributed by the UEFI or the OS. And several PCI devices share one interrupt through the distribution of UEFI or OS.

Appendix Troubleshooting and Solutions NO. Phenomenon 1 BIOS setting cannot be saved 2 The computer can only be powered-on occasionally 3 When connecting with a USB flash drive, the system prompts that a high-speed device has been connected with a low-speed connector. 4 The screen has no display after replacing with a new memory and cannot enter system; even when the former memory is re-installed, the system cannot be booted as well.
Appendix 5 The system cannot be booted after replacing a CD-ROM. 6 No PCI card can be detected after entering the system. 7 No peripheral devices can be detected. - 54 - system will be booted smoothly. Analysis: the data cable of the hard disk may get knocked when installing the CD-ROM, which leads to poor connection of the hard disk data cable, or the master and slave jumpers on hard disk and CD-ROM are wrongly set.
