Cache Memory The Pentium microprocessor includes 16 KB of cache on the chip. The 82430HX PCIset includes a cache controller that supports direct-mapped cache memory and supports a second level cache that uses up to 512 KB of Synchronous Pipeline Burst SRAM. IDE Peripheral Interface The motherboard provides a high speed, 32-bit PCI/IDE interface.

Index boards use the same interrupt resources as ISA add-in boards, you must specify the interrupts used by ISA boards in the Setup program. Chapter 2 tells how to use the Setup program. The PCI auto- configuration program complies with version 2.1 of the PCI BIOS specification. IDE Auto-configuration If you install an IDE drive in the system, the IDE auto-configuration utility automatically detects and configures the drive for operation in the system.

Serial Port 1 Address Selects the address and IRQ of serial port 1. The options are Disabled; COM1, 3F8h, IRQ4; COM3, 3E8h, IRQ4; and COM4, 2E8h, IRQ3. The default is COM1, 3F8h, IRQ4. If the Configuration Mode is set to Auto, the Setup program assigns the first free COM port (normally COM1, 3F8h, IRQ4) as the serial port 1 address and IRQ, regardless of what is selected under the Serial Port 1 Address option.

This field should be set to Enabled only when a non Plug and Play ISA card (legacy card) that requires non-ROM memory space is used. LAN cards that have on-board memory buffers are one example of this; video capture cards that have video buffer memory are another. By default, allocation of upper memory is as follows: memory from C0000-C7FFF is automatically shadowed.

Unattended Start Controls when the security password is requested. The options are Enabled and Disabled. The default is Disabled. The User password must be enabled before you can enable this option. If Enabled is selected, the system boots, but the keyboard will be locked until the User password is entered.

Page 48: Bios Update And Recovery
Index Bios Update and Recovery BIOS Update The system BIOS resides on a flash component. You can upgrade a flash BIOS through software, without taking the system apart or replacing the flash component. This appendix tells how to upgrade your system BIOS from a diskette. The appendix also tells how to recover from an interrupted upgrade.
