gm300的某个版本的写频软件确实不能再高主频下写，我已经证实，造成的原因是由于当年的tp7编译语言环境的一个函数有问题,
这个问题统称为
fix for "runtime error 200" bug of borland pascal 7 on fast pcs
borland turbo pascal 7 is a great pascal compiler for pc's. unfortunately it has not been updated by borland for many years (for a possible alternative see fpc).
all programs compiled with borland pascal 7 that use the system unit crt (almost all programs do that) abort with the error message "runtime error 200" on all fast pcs, for example pentium ii with 233 mhz.
programs compiled with borland pascal 6 are said to not abort with a runtime error, but their delay is completely wrong on fast pcs (and the problem starts there at much lower speeds than the problem of version 7).
this web page tries to explain the problem and summarize some existing solutions.
补丁我有，需要常驻内存使用，有需要可以发给大家··！
我想说的是，确实有很多当年的程序不能运行在高主频下的cpu上，即使在虚拟机或者实模式的dos下也不行！！
另：dosbox这个软件不错，除极个别的台子不能写（目前我只发现p200\ht600不能写）其它在dos下写频的基本都可以写···很方便不需要启动虚拟机，也不需要重新启动主系统，而且添加软件方便，推荐大家使用···
最后还有dosbox可以解决上面的问题，他可以更改模拟的dos的cpu的速度，呵呵
