不行啊单但这么写 我只能调用80来k的UMB
后来看了一下开机时hiram的那张图 看见ca00-efff好象都是可以调用的
然后我就写了 i=cc00-efff 分别用了emm386和umbpci （都运行了ccdos）

我又照了umbpci的说明 这样写：

device=Hiram.exe

但是ccdos运行不了了 为什么？？

It doesn't work. Just writing like this, I can only call 80-some KB of UMB.
Then I looked at the picture of hiram at startup and saw that ca00-efff seemed all callable.
Then I wrote i=cc00-efff and used both emm386 and umbpci (both ran ccdos).
