Hi list,

I tried to install RHEL3 U7 in my x64 machine through PXE,
but the The PXE installation process stopped when loading
initrd.img. It shows like below and stops:

kernel /rhel3_u7-x86_64/vmlinuz
   [linux-bzImage,setup=0x1400,size=0x1638d5]
.initrd /rhel3_u7-x86_64/initrd.img
..   [Linux-initrd @ 0x37cd9000,0x316529 bytes]

My question is: is there any way to get more information
when initrd.img stops? so that I can debug the problem.
The debugging mechanism available in this early boot
stage is very limited, and I don't know how to deal with it.


Well, On thing u can do is that unzip  ur initrd image...
There is a script init, add some print statements after every executable line
and try to catch up...

Thanks,
Forrest
