From bf38b1ddea618cb3b9c9c46d51c6d3523f11ed35 Mon Sep 17 00:00:00 2001 From: ru Date: Thu, 30 Sep 2004 09:59:44 +0000 Subject: Fixed desctiptions of some options: - Document better what the -C option means. - The -c option is currently a no-op. - The -D and -h options do not allow switching between single/dual console modes and internal/video consoles. (This used to be true for the old biosdisk boot code, but now they just force the multiple consoles mode and serial console, respectively.) --- sbin/reboot/boot_i386.8 | 24 ++++++------------------ 1 file changed, 6 insertions(+), 18 deletions(-) (limited to 'sbin/reboot') diff --git a/sbin/reboot/boot_i386.8 b/sbin/reboot/boot_i386.8 index 56ea285..8dfd5d8 100644 --- a/sbin/reboot/boot_i386.8 +++ b/sbin/reboot/boot_i386.8 @@ -195,20 +195,13 @@ Boot flags: during kernel initialization, ask for the device to mount as the root file system. .It Fl C -boot from CDROM. +try to mount root file system from a CD-ROM. .It Fl c -run UserConfig to modify hardware parameters for the loaded -kernel. -If the kernel was built with one of -.Dv USERCONFIG , INTRO_USERCONFIG , VISUAL_USERCONFIG -options, -remain in UserConfig regardless of any -.Ic quit -commands present in the script. +this flag is currently a no-op. .It Fl D -toggle single and dual console configurations. +boot with the dual console configuration.
