IDE on Sandpoint

[ZHANG,HAI-TAO (Non-A-China,ex1)]

Hi,

Thanks for your help. I have tried the new 2.4 source and make the kernel
boot, but the kernel crashs when initializes the Intel eepro100 network
card.

Here is the message:

I am using kernel 2.3.16 before, its driver of eepro100 works well. I am
tring to fix it, any suggestions?

Thanks,

Yes, I had to make some minor changes to the driver to get ide to work (plus
add support to sandpoint_setup.c).

Go to ftp://www.mvista.com/pub/Area51/sandpoint-8240/  and get
sandpoint.linux.tar.gz.  This is a tarball of kernel source that has IDE
working (at least on an 8240 and a 755/107).  I just put it there so let me
know if you have any problems ftp'ing it or its corrupted or something.

This kernel routes ide interrupts to the standard ISA/8259 IRQ's, namely 14
&
15.
