kernel debug under bochs

[xuedan]

Hi Friends,

I successfully build the 2.6.21 under fedora 7. I like to debug the kernel under Bochs. I build the Bochs under fedora 7 with gdbstub enabled. With bochs tools, I can create "img" file and partition it as Linux/minix . But how to transfer the built kernel into this "img" file? I means how to let the kernel start it?

Thanks

You must have a loader first .

Place the image into a disk where the loader can find it .

eg: place the image in the rootfs and edit the menu.lst if
grub.

I happen to realize I must create the root system so that kernel can find the residence. But how to create the root system?

1: use bximage command to make a hard disk image
2: use mke2fs command to make ext2/ext3 filesystem on
the image
3: creat some directorys and files like "/bin" "/etc/rc" ,etc.

Then you can use the loader to load the kenel on the disk image.
hope it can work.

Good luck!

Tell me when you get it.

I still have trouble of installing grub on the image HD created by bximage.

I install it but no response when booting it.

Is there any advice?

Thanks
