LFS Live CD 引导问题

mech

刻的光盘在引导时，估计是到挂载光驱时不能通过，出错。
用Gentoo的Live CD也是这样，但是gentoo引导时可以加参数 ide=nodma 完成引导。
ubuntu也不能通过。
其他的光盘比如kanoppix就可以正常引导、windows也是好的。

LFS CD引导有没有类似的参数？

有什麽错误信息？

光驱是否外置的？

启动时改用 linux.ata 看看是否可以

mech

inner cd-rom, Mida 50xB

message:
<0>Kernel panic - not syncing: Fatal exception in interrupt

where to use linux.ata ?

I input "linux.ata" after "boot:", but it say that there is no kernel named linux.ata .

It is not use dma in knoppix live CD by default.
It is halt when I input the parameter "knoppix dma" .

Is that means that it must not use DMA in linux's kernel when boot from live-cd ?

No "linux.ata" means your LiveCD is rather old, it is included since 6.2.

However, as you are using a "inner cd-rom" (internal CDROM?), may be you don't need such option.

Knoppix does use DMA by default, if you don't want to use DMA, you should start it with nodma.

I cannot remember whether it has an option to disable DMA in LFS LiveCD, but I don't have a LFS LiveCD handy and I cannot tell you now.

我的LFS live CD 是6.2-5的，特意下的最新的。
郁闷啊，在vmware里面很正常的

若如此就是硬件问题了，看看 BIOS 里有没有什麽可设定的？

怀疑cdrom的dma有问题，没办法修的。
我另外一个光驱就可以正常的引导。问题是这个光驱差不多坏了，我要把它的外壳、电路板都拆开才能用。哈哈，裸奔啊

今天的高速 DVD writer 也才两百多，扔了它算吧
