hi there,

its been ages now that i have posted a query..i just wants to know how to remove the already installed KDB patch? is there any command?

The second basic doubt is what is difference between i386 and x86 arch as i have to reinstalled the KDB, previously i tried downloading patches for x86 but it wont work.my system got hang.

Seeking your valuable guidance always.

Hi Guarev,

If you have the patch file which was used to apply the patch, you can simply un-patch the code using the `patch` command. It will reverse the patch.

As for the x86 issue: i386 is the (usually the) earliest compatibility level you will find for x86 architectures. As CPUs got more advanced, they moved to i486, i586, i686, etc.. A 386-level computer will not necessarily run code that is compiled specifically for > a 386 processor. Essentially, it is backwards compatible, but not forward compatible.

Try Googling for something like "Intel x86 architecture" and you should quickly locate a good Wikipedia article that explains the x86 architecture.

Good luck!

any examples how to use that 'patch' command....to unpatch d kernel..

Gaurav Holey

Well, lets say you patched the kernel, with a patch-file named "hello", like so:

shell# patch -p1 -i hello

Then, to reverse that patch, either do the same command again and answer the question it asks you when it detects that the patch was already applied, or try using the -R option, which means "reverse", like so:

shell# patch -p1 -R -i hello

Check out the man page for patch:

shell$ man patch
