[edit] Install a new kernel
To be able to install a new kernel, first edit /etc/netpkg.conf and search for the line starting with "Black_list" and remove "kernel kernelsource ndiswrapper" from that line, leaving only "aaa_base", save the file.
NOTE: In ZW 5.2, this line only reads aaa_base --Jay.Goldberg 17:00, 8 January 2009 (MST)
Type:
netpkg kernel ndiswrapper
and follow the instructions given by the netpkg to upgrade to the new versions.
Just to make sure...run
root# lilo -v
The new kernel should be installed by now. Put back the configuration files has they were: edit /etc/netpkg.conf yet again Search for the line starting with "Black_list" and add "kernel kernelsource ndiswrapper" to the end of that line, as it was before. After a reboot the new kernel should be enabled :)
[edit] Miscellaneous Instructions
To upgrade from a kernel < 2.6.19 to a kernel >= 2.6.19 some factors need to be taken care of. To the use of the libata disk subsystem, if using IDE/PATA/ATA devices some configurations need to be made.
- In a system only with IDE/PATA/ATA devices
Simply change all device names in /etc/fstab from /dev/hdXY to /dev/sdXY edit /etc/lilo.conf and make the same procedure change all device names from /dev/hdXY to /dev/sdXY except the "boot =" line
the next lines assume that you have Zenwalk installed on /dev/hda1, change to whatever you have in your system
mount /dev/hda1 /mnt # this is needed to bypass the filesystem partition check, since /dev/sda won't exist yet lilo -v -P ignore -r /mnt/
You can now reboot your system, with Zenwalk.
some changes still need to be made, edit /etc/lilo.conf yet again and change the device name in the "boot =" line from /dev/hdXY to /dev/sdXY and run
lilo -v
[edit] Considerations
Some considerations to these procedures
- If using multi-boot
You should comment all windows partitions(all 3 lines) from /etc/lilo.conf before running "lilo -v -P ignore -r /mnt/" and after the reboot remove those comments, example:
other = /dev/hda1 label = WindowsXP table = /dev/hda
- Upon removing those comments, you should change it to something like:
other = /dev/sda1 label = WindowsXP table = /dev/sda
- Your /etc/fstab should also be edited on the cdrom line, something like:
from: /dev/hdX /mnt/cdrom iso9660 noauto,user,ro 0 0 to: /dev/sr0 /mnt/cdrom iso9660 noauto,user,ro 0 0
- If using mixed SCSI/SATA and IDE/ATA/PATA disks on the same system
The SCSI/SATA devices will remain unchanged; The IDE/ATA/PATA will change to /dev/sdX, but be advised that it won't be so linear, example:
- In a system having a SATA and a IDE drive
The SATA device name will be /dev/sda(as it was) but the IDE device will become /dev/sdb), if you have two SATA disks and one IDE disk, the SATA devices will be /dev/sda and /dev/sdb (as it was) but the IDE device will become /dev/sdc, and so on...
[edit] Known Problems
If you get this kind of error, or similar:
BIG FAT WARNING!! failed to translate "dev/hda2" into a device id. Press SPACE to reboot or C to continue booting this kernel. Default action if you don't select one in 25 sec: continue booting
and/or
VFS: Cannot open root device "307" or unknown-block(3,7) Please append a correct "root=" boot option kernel panic-not syncing:VFS:Unable to mount root fs on unknown block(3,7)
the procedure is a bit different, in this case, boot from a LiveCD/DVD, assuming you have Zenwalk installed on /dev/hda1:
mount /dev/hda1 /mnt
Simply change all device names in /mnt/etc/fstab from /dev/hdXY to /dev/sdXY edit /mnt/etc/lilo.conf and make the same procedure change all device names from /dev/hdXY to /dev/sdXY except the "boot =" line
lilo -v -P ignore -r /mnt/
You can now reboot your system, with Zenwalk.
some changes still need to be made, edit /etc/lilo.conf yet again and change the device name in the "boot =" line from /dev/hdXY to /dev/sdXY and run
lilo -v
