Problems in using loadLin

Problems in using loadLin

[chen, xiangping]

Hi,

I am trying to use loadlin to boot up a machine. But after I 
replaced the bzImage, the kernel fails to boot up. It prints 
out error messages like:
	...
	VFS: Mounted root (ext2 filesystem) readonly
	Freeing unused kernel memory : 96K freed
	Warning: unable to open an initial console
	Kernel panic: No init found. Try passing init= option to kernel.

The boot.bat file is:
	loadlin.exe bzImage ro root=0x0821

Thanks,

Xiangping

0x0821 represents /dev/sdc1. Did you build the SCSI driver into the kernel, or
do use an initrd?

Hi,

Thanks for the reply. I found the problem. The first kernel
image doesn't probe multiple luns, while the second one does.
So the devno of the root filesystem changes. I built the driver
into the kernel, so I did not use the initrd.

There is another problem with loadLin for > 2.4.2 kernel. 
It seems that I could not use dev names to specify root 
filesystem. Say if the boot.bat is like:
	loadlin.exe bzImage ro root=/dev/sdc1

The kernel fails to boot due to null ptr error.

0x0821 represents /dev/sdc1. Did you build the SCSI driver into the kernel,
or
do use an initrd?
