【摘要】 无盘工作站是靠网卡上的Bootrom芯片来实现远程启动功能的，从1994～2005年，它已经历了3个技术发展阶段，即：以DOS为主的预启动执行环境(IPX)无盘站，以Windows 95为主的RPL无盘站和以Windows 98、Windows2000为主的预启动执行环境(PXE)无盘站。其中PXE是真正意义上的远程启动技术，虽然它推出时间不短，但真正有价值的应用却是近两年才体现。本文针对有盘工作站在医院HIS网络系统应用中的诸多弊端(如维护工作量大、安全性低等)，成功应用PXE技术，提出了无盘工作站的解决方案，极大地方便了医院信息系统(HIS)网络系统的管理和维护，并举例说明了其实现过程。

    【Abstract】 Diskless workstations realize remote booting with the help of the chip bootrom in the network card. Since 1994, technically it has gone through three stages of development: IPX based on DOS, RPL based on Windows 95, and PXE based on Windows 98 & 2000. Of the three, PXE is the only remote booting technology of real significance. Although it was brought forth long ago, it is only within the last two years that its applications of real value have been discovered. Considering that application of workstations with disks in hospital information system (HIS) has many disadvantages, such as huge maintenance work involved and poor performance in safety, this paper deals with diskless workstation solutions based on successful application of PXE technology for convenience of HIS management and maintenance, and gives examples for its processes. ......
