[mpeg2] Re: ADSPCodeLoad failure continued

[Goldfish <kkleung1@cse.cuhk.edu.hk>]

Hi,

	I have also tried all the way you have done but it still not
work... :-(

	Moreover, I have also disabled the USB in the BIOS setup (actually
I never enable it, and re-compile the kernel with USB disabled), but still
the same problem.

	One thing I want to ask Frank, has your card worked before? Have
you successfully encoded a mpeg file before? If so, what is the setting
and what version of driver you use at that time? Also is the problem of
ADSP loading failure related to the On/Off of USB in BIOS?

Regards,
goldfish
