Lilo

====== lilo bootloader ======

LILO (Linux Loader) is a boot loader for Linux and the default bootloader for non EFI slackware installs.

we need multiple kernels to boot. whether you run stable or -current you want to always have a known working kernel to fall back on. first we will install the kernels of your choice using slackupdr

https://wigums.ddns.net/dokuwiki/doku.php?id=slackupdr

once your kernels are installed edit lilo.conf

nano /etc/lilo/conf

find the kernel stanza and we will expand it to include the new kernels. we are also going to add boot entries for huge versus generic kernels. find this stanza

# Linux bootable partition config begins image = /boot/vmlinuz root = /dev/sda2 label = huge read-only

we will add stanzas for the kernels we've installed

here is a default lilo.conf as generated by liloconfig

# LILO configuration file

Append any additional kernel parameters:

append=" "

boot = /dev/sda

This option loads the kernel and initrd much faster:

Boot BMP Image.

Bitmap in BMP format: 640x480x8

bitmap = /boot/slack.bmp

foreground, highlighted background, highlighted shadow):

bmp-colors = 255,0,255,0,255,0

Location of the option table: location x, location y, number of

columns, lines per column (max 15), "spill" (this is how many

entries must be in the first column before the next begins to

be used. We don't specify it here, as there's just one column.

bmp-table = 60,6,1,16

Timer location x, timer location y, foreground color,

background color, shadow color.

bmp-timer = 65,27,0,255

#message = /boot/boot_message.txt

Wait until the timeout to boot (if commented out, boot the

first entry immediately):

prompt

Timeout before the first entry boots.

This is given in tenths of a second, so 600 for every minute:

timeout = 1200

Override dangerous defaults that rewrite the partition table:

change-rules reset

Normal VGA console

vga = normal

Ask for video mode at boot (time out to normal in 30s)

#vga = ask
