关于多分区的加载问题

[lxjlan]

目前的NAND 除了reserved 的 block(STEPLDR, TOC, EBOOT), MBR, 之后把剩下的NAND分成4个区， 一个BINFS分区, 3个FATFS分区。
MBR的4个分区的数据如下：
03 05 01 00 21 c4 00 00 40 01 00 00 00 30 00 00
00 c5 01 00 0b e4 00 00 40 31 00 00 00 08 00 00
00 e5 01 00 0b e4 00 00 40 39 00 00 00 40 00 00
00 e5 01 00 0b e4 00 00 40 79 00 00 00 40 00 00

注册表里的配置如下：
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SMFLASH]
"Prefix"="DSK"
"Dll"="smflash.dll"
"Index"=dword:1
"Order"=dword:0
"Profile"="SMFLASH"
"IClass"="{A4E7EDDA-E575-4252-9D6B-4195D48BB865}"
"Flags"=dword:00000014

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\SMFLASH]
"PartitionDriver"="mspart.dll"
"Folder"="NAND_FLASH"
"AutoMount"=dword:1
"AutoPart"=dword:1
"AutoFormat"=dword:1
"Name"="Microsoft Flash Disk"

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\SMFLASH\BINFS]
"DLL"="binfs.dll"

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\SMFLASH\FATFS]
"DLL"="fatfsd.dll"

这样能否在NK启动的时候把4个分区都mount上去呢？
由于我的NK，是无界面的 ，所以debug起来比较麻烦。
在系统默认的情况下， NAND在download NK的时候，被分成了2个区， 一个NK.bin大小的文件的BINFS分区和剩下的部分分成一个FAT的分区用于用户数据，这样的情况下， 在系统上看， NAND驱动器被识别为xxxx(不知道这个名字是靠哪个键值来定义的)，分区一显示为Part00, 第二分区为Part01* (这里的*是什么意思？)， 这个时候挂载到系统的路径是不是 \"Folder"\ (Folder取决于注册表的配置)， 但是这样就有个问题了，如果像我这样的的3个分区都被挂载了，那路径是如何的？

顶下。。。 为啥没人帮忙呢？　难道是我的问题描述得有问题？

[unsway123]

在存储管理器上看你的nandflash的名字就是name Microsoft Flash Disk,你挂在上去的part00是挂载上去的名字，也就是那个folder,所以你的路径应该是\Microsoft Flash Disk\floder

如果是APP来读写数据都是需要靠这样的路径来寻找文件的。

我不知道你的注册表是基于hive还是基于RAM，如果是基于hive我敢打包票你的注册表肯定是起不来的。如果是RAM我就不好说了。因为我没有试验过。。如果兄台想要验证你的想法。。不用debug也可以看到你的分区时否挂上啊。。。可以telnet啊。。。

仅仅这些注册表内容吗？
如果想实现三个FAT分区，那么FAT分区部分的注册表就要写三个，且驱动要支持。不同的路径都是通过每个folder来设置的

啊。。 是要3组的呀？ 我好好研究下你的 reg信息， 非常感谢各位。

[/Quote]

这样设置了其实的扇区和大小的方式， 系统的能识别他们是同一个MBR上所定义的吗？
还有一个疑问的地方，"AutoMount"=dword:1　这个参数，我在手册上看到，　如果定义了这个会自动mount所有的分区， 这个会和上面的设置冲突造成紊乱吗？
