4 Real time clock with 256Byte CMOS SRAM. 实时时钟 1.3 PCI AUTO-Configuration Capability(PCI 自动配置性能 ) The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow the insertion and removal of PCI cards to the system without user intervention. When the system is turned on after adding a PCI add-in card, the BIOS automatically configures interrupts, DMA channels, I/O space, and other parameters. The user does not have to configure jumpers or worry about potential resource conflicts. PCI cards use the same interrupt resources as ISA cards, the user must specify the interrupt used by ISA add-in cards in the Setup utility. The PCI Auto-Configuration function complies with the PCI BIOS specification. PCI 自动配置功能可以在关电后插上或挪开 PCI 卡而用户无须担心插上 PCI 卡加电, BIOS 完全自动给它配置中断 DMA 通道 I/O 地址及其它参数, 用户无须跳线也不要担心资源冲突 1.4 ISA Plug & Play Capability(ISA 即插即用功能 ) The BIOS incorporates ISA Plug and Play capabilities conforming to the Plug-n-Play specification. This will allow auto-configuration of Plug and Play ISA cards, and resource management for legacy ISA

cards, when used in conjunction with the ICU, ISA Configuration Utility.
