问题：有个朋友，本本是toshiba的portege 100, 超薄的那种，没有光驱，只有一个usb软驱和u盘一支。不知道玩什么不慎，搞得没法启动，要重装系统。
重装系统步骤：
[*] 到 >>新dos时代<< 下载msdos "7.10" (呵呵，应该不是官方的东西)
[*] 下载 >>mhairudos.zip (panasonic提供的通用usb设备驱动)<< , 将其中的usbaspi.sys, di1000dd.sys解压到比如c盘根目录。

let me mention that legalese on the Panasonic site most probably prevents you from downloading and using this driver on non-Panasonic devices, yet according to reports that are floating around on the Interweb, people have been able to use these "universal drivers" on a wide range of systems with different USB connectivity, UHCI, OHCI, and USB 2.0's EHCI with the NEC chipset.
The Panasonic DOS drivers seem to work on most USB chipset implementations, including Intel and NEC, as well as NVidia, VIA, and SIS. It seems Panasonic engineers didn't want to have to write a driver every time for every different chipset, so they wrote this "universal" driver to work with all possible USB controllers.
[*] 在config.sys中添加：
Quote:
device=c:\usbaspi.sys
device=c:\di1000dd.sys
[*] 重启，记得需要在系统启动前插上u盘。一般来说这样就可以使用u盘了，可以用来在台机和本本之间对考数据（备份文件，安装文件，etc）
建议：在这种无光无软的本本上应该留一个小分区（比如50M）给应急系统（legacy MS-DOS, FREEDOS 或者linux），并且配备必要的工具 (PQMagic, DM, HD-COPY, ghost, nc, ntfsdos, ...)
