Boot loader code

6.10 LPAR mode z/VM guest KVM guest

A kernel image is usually compiled to contain boot loader code for a particular boot device.

For example, there are Linux® configuration menu options to compile boot loader code for tape or for the z/VM® reader into the kernel image.

If your kernel image does not include any boot loader code or if you want to boot a kernel image from a device that does not correspond to the included boot loader code, you can provide alternate boot loader code separate from the kernel image.

You can use zipl to prepare boot devices with separate DASD, SCSI, or tape boot loader code. You can then boot from DASD, SCSI, or tape regardless of the boot loader code in the kernel image.
