Red Hat Training
A Red Hat training course is available for Red Hat Enterprise Linux
44.6.5. IBM eServer pSeries Systems
IBM eServer pSeries systems use YABOOT as the boot loader, which uses
/etc/aboot.confas the configuration file. Confirm that the file contains an
imagesection with the same version as the
kernelpackage just installed:
boot=/dev/sda1 init-message=Welcome to Red Hat Enterprise Linux! Hit <TAB> for boot options partition=2 timeout=30 install=/usr/lib/yaboot/yaboot delay=10 nonvram image=/vmlinux--2.6.9-5.EL label=old read-only initrd=/initrd--2.6.9-5.EL.img append="root=LABEL=/" image=/vmlinux-2.6.9-5.EL label=linux read-only initrd=/initrd-2.6.9-5.EL.img append="root=LABEL=/"
Notice that the default is not set to the new kernel. The kernel in the first image is booted by default. To change the default kernel to boot either move its image stanza so that it is the first one listed or add the directive
defaultand set it to the
labelof the image stanza that contains the new kernel.
Begin testing the new kernel by rebooting the computer and watching the messages to ensure that the hardware is detected properly.
