写0BANK技术
可写的地址是 00 bank页的 $8000-$ffff,其中包括BIOS和中断源地址，RESET/IRQ/NMI中断例程，双机修复/系统检测程式等等等等
注意:
1.写之前必须保证电力充足，否则后果严重
2.请勿使用此程序编写任何破坏性程序，否则一切后果自负！！！！！
3.因为使用此程序造成的一切后果，笔者概不负责（压缩包中的程序已经通过测试）！！
4.程序适用于 nc2600/nc2000,不保证适用于nc3000
总之大家请小心用！因为0BANK里保存的是非常重要的资料，改他们很有用，同时也很危险！！
如果你还是个菜鸟，建议谨慎使用，因为可能导致连双机修复都无法恢复的严重错误！！！

源代码 :
nc2600/2000写0bank
将bank0的$9097的"NandCheck"改为"闪存检测 ",完成后自动重开机
程序必须在sdram
比如从$1000开始
msg:"闪存检测 "
