Seekfor FAT system v1.2是移植性非常强的一个嵌入式FAT16/FAT32文件系统软件包,支持多个物理驱动器,完全兼容DOS下的文件系统,支持多任务下的文件操作.
<1>和SFS v1.0比较,SFS v1.2增加以下特性:
	1.增强了错误处理功能
	2.增加了FAT_format()功能
	3.开始支持扩展分区
	4.开始支持长文件的显示(暂不支持用长文件名访问文件),Windows下建立的长文件名可以正常显示
	5.取消v1.0中的物理驱动器概念,所有驱动器都看做逻辑驱动器
	5.修正v1.0中扇区计算不对不兼容Windows的bug
	6.修正FAT32根目录起始位置固定的bug
<2>更新软件请联系:
	QQ:82054357
	MSN:[e-mail]
	Mail:[e-mail]
<3>本文件说明
	a.文件名:portable.c
	b.功能:用户自定义函数,用来实现不同系统的移植
