load module ahci ？

kwindva

开机时，这个module载入最慢。而我的主板是intel ich 7的，不支持ahci，在bios里只有raid模式可选。
于是我觉得可以在编译内核时把ahci模块取消，结果出现
Determining root device...
Block device /dev/sda1 is not a valid root device ...
Could not find the root block device in.
把ahci模块编上，启动时载入它就没事了。
很奇怪，我的机器和ahci无缘，为何一定要载入它呢？

你在BIOS里面设置的是IDE模式还是RAID模式？
RAID模式会自动打开ahci功能
如果不建RAID的话其实IDE模式更好些

是吗？我在bios里是选的raid模式，不过网上说我的主板（即intel ICH7)不支持ahci啊。好奇怪。

lspci 看一下，有没有 AHCI Controller 就知道了。

lspci里没有AHCI。为何我还不能丢掉这个模块？
