4.1 x86_64 doesn't contain a mkbootdisk rpm Then, How do I make a bootdisk easily ? (I know how to use grub to make the bootdisk.) But any other easier method ?

Thx !

There is a mkbootdisk rpm .. it the kernel just won't fix on a floppy ...

http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/mkbootdisk-1.5.2-1.i38...

Since mkbootdisk is not in the x86_64 release, yum fails to find it. A minor inconvenience and possible source of confusion as it can be installed with rpm from the above link or a local copy; or in my case, I linked from a local x86_64 repo to the mkbootdisk rpm in the i386 repo so it can be found by yum (after creating a /etc/yum.repos.d/local.repo file and running createrepo, of course).

OK, this time I will type more slowly and proof read it before I press send :)

mkbootdisk exists (see the above link), but the kernel is too large to fit on a floppy, so the image created will not fit on a floppy.

You must be root to use mkbootdisk (or use /sbin/mkbootdisk)

You will have to use the --iso option

Presumably only for an ISO image.

Does give a strange error, but works...

# mkbootdisk --iso --device boot`uname -r`.iso `uname -r` Unknown file type (unallocated) /tmp/mkbootdisk.de4575/.. - ignoring and continuing.

and create either a CD, usb key, or other > 2mb device image

For this approach, you don't want the --iso switch, and 2mb may be a bit small. After a few iterations...

[root@wx1 ~]# mkbootdisk --device boot`uname -r`.img --size 3000 `uname -r` cp: writing `/tmp/mkbootdisk.IG5011/initrd.img': No space left on device cat: write error: No space left on device cat: write error: No space left on device [root@wx1 ~]# rm boot2.6.9-11.ELsmp.img rm: remove regular file `boot2.6.9-11.ELsmp.img'? y [root@wx1 ~]# mkbootdisk --device boot`uname -r`.img --size 3500 `uname -r` [root@wx1 ~]# ll total 7180 -rw-r--r-- 1 root root 1387 Jun 17 13:06 anaconda-ks.cfg drwxr-xr-x 3 root root 4096 Jun 20 13:35 bin -rw-r--r-- 1 root root 3584000 Jun 20 14:03 boot2.6.9-11.ELsmp.img -rw-r--r-- 1 root root 3608576 Jun 20 13:57 boot2.6.9-11.ELsmp.iso

Many PCs BIOS settings don't allow booting from a usb key.
