[. . . ] Onboard I/O interfaces comprise of two UART 16550 serial ports, a parallel port with ECP/EPP feature, and PS/2 keyboard and mouse ports. As added enhancements, the board also incorporates a Sound Blaster Pro-compatible audio subsystem plus plug-and-play (PnP), power management, and software shutdown features.

The slot board carries the PCI and ISA bus slots for system enhancements and future expansion. The slot board may vary in size and layout depending on your system housing. [. . . ] Refer to Table 1-1. 1-18 User's Guide 1. 7 Video Memory Upgrade Larger video memory allows you to display higher resolutions and more colors. The system board comes with a 1-MB video memory onboard upgradable to 2 MB. 1. 8 Second-level Cache Configuration The system board supports 256-KB or 512-KB pipeline burst secondlevel cache. Table 1-8 shows the second-level cache configurations. Note that the cache is mounted onboard and not user-upgradable.

It has connectors onboard to accommodate the audio-I/O board, WaveTable, CD-ROM, and fax-voice modem. You may disable the audio feature in the BIOS Utility. 1. 9. 1 Installing the Audio-I/O Board The connector CN4 on the system board accommodates the audio-I/O board. See Chapter 2 for more information on the setting description. 1. 10. 1 QuickStart Mode Operation At any time while the system is running, enter the QuickStart mode by simply pressing the power switch for less the four seconds. This action causes the system to rest (QuickStart state 1) by turning off the keyboard, mouse, and monitor. After the specified time in the QuickStart State Timer parameter in BIOS, the system sleeps (QuickStart state 2) and turns off the hard disk. Once the system enters QuickStart mode, the hard disk/message LED and keyboard LED go off, while the power and monitor LEDs start blinking. When a message comes, the hard disk/message LED starts blinking orange, then green when the hard disk reads the message. After getting the message, the hard disk and the LED go off again. Press the power switch again for less than four seconds to return to the normal mode. To enter or exit the QuickStart mode, make sure to press the power switch within four seconds. Pressing it for more than four seconds turns off the system. 1-24 User's Guide 1. 11 Installing ISA Cards Both PnP and non-PnP ISA cards require specific IRQs. When installing ISA cards, make sure that the IRQs required by these cards are not previously assigned to PCI devices to avoid resource conflicts. Follow these steps when installing ISA cards: 1. Remove all PnP cards installed in the system, if any. Use Windows 95 or ICU to manually assign the appropriate IRQs to the cards. This ensures that BIOS will not use the resources assigned to the non-PnP ISA cards. BIOS detects and configures only PnP cards. 5. This time PnP BIOS automatically configures the PnP ISA and PCI cards with the remaining free IRQs. System Board 1-25 1. 12 Error Messages Do not continue using the computer if you receive an error message of any type. Note the message and take corrective action. [. . . ] You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. An incorrect configuration is a major cause of power-on error messages, especially for a new system. Check that the jumpers on the system board and any expansion boards are set correctly. If you cannot access a new disk, it may be because your disk is not properly formatted. [. . . ]
