笔者最近组装了一台兼容机,其配置为:钻石586ITXD主板,Pentium 200MMX CPU,32M SDRAM 内存,3.2GMaxtor Ultra DMA(83240D3)硬盘,联讯Canarias2000显示卡,16XBTC光驱,创通SB 16PnP声卡,33.6K内置Fax/Voice/Data Modem,14英寸三星SyncMaster 400b彩显,银河ATX机箱。 这次购机主要考虑的是速度问题,所以特意选择了支持Ultra DMA的主板和硬盘。Ultra DMA采用总线主控方式,在硬盘上带有DMA直接内存访问控制器。由于在数据传输过程中不需要CPU干预,因而能节约宝贵的CPU资源,从而提高系统的运行速度。其次,Ultra DMA把IDE
The author recently assembled a compatible machine, the configuration is: Diamond 586ITXD motherboard, Pentium 200MMX CPU, 32M SDRAM memory, 3.2GMaxtor Ultra DMA (83240D3) hard drive, the Canaryas2000 graphics card, 16XBTC drive, creators SB 16PnP sound card, 33.6 K built-in Fax / Voice / Data Modem, 14-inch Samsung SyncMaster 400b color display, Galaxy ATX chassis. The purchase is the main consideration is the speed of the problem, so specifically chose to support the Ultra DMA motherboard and hard drive. Ultra DMA uses bus mastering with DMA direct memory access controller on the hard disk. As the data transfer process does not require CPU intervention, which can save valuable CPU resources, thereby increasing the speed of the system. Second, Ultra DMA IDE
