MS-DOS 7.1 下加载U盘驱动的最好方式：

在autoexec.bat文件中加入如下几行:

devload usbaspi.sys /r /v /norst

devload usbcd.sys /d:usbcd

devload di1000dd.sys

SHSUCDX.COM /D:?USBCD

其中devload di1000dd.sys　用来驱动大容量U盘，devload usbcd.sys /d:usbcd 和SHSUCDX.COM /D:?USBCD用来驱动USB光驱。

其中devload usbaspi.sys在某些机器上死机的问题已经解决。usbaspi.sys 为2.27修改版。

其中devload di1000dd.sys出现devide overflow的问题及不兼容USB-ZIP+的问题都已修正，版本改为2.02以示区别。
