I have a Gateway 2000 P4D-100. It has a built in CMD640.
A 1G disk and a NEC cdrom at ide0 and a 540 M DISK at ide1.
Even with the chip enabled, the 1.3 kernels cannot reset the second ide.
In 1.3.59 it was possible to set CMD640_NORMAL_INIT to 0 in cmd640.c,
but this option is dissapeared in the later versions. Although I
found the part in the cmd640.c file wich can be disabled in 1.3.59, I
do not know if it is save to disable this part in the later versions.
By the way, with a high load on the disks, the system often hangs, while the
disk light is burning. I thought it was due to the CMD640B, and I am thinking
in buying another ide chip. But I read that also other chipsets have the same
problem.
Cheers,
Dirk Peter
