Boot loader code

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest KVM guest

Red Hat® Enterprise Linux® 9.2 kernel images are compiled to contain boot loader code for IPL from z/VM® reader devices.

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.

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.
