- Added support for "dual" internal/serial consoles (-D flag). If -D is set, then all i/o from the boot blocks is to and from both the internal console and the serial console. -D has no effect on the kernel (-h decides the kernel serial console as usual). -D should normally be set in /boot.config. - Get help messages from /boot.help. You should copy boot.help from the biosboot directory to the root directory on the boot drive when you install new boot blocks. - New, less invasive keyboard probe. Enable keyboard probe dynamically (-P flag). Should probably never be used (use -h instead). - Fixed/improved initialization from boot.config. It didn't interact correctly with the NAMEBLOCK option, and the initialization of the drive/unit/partition didn't stick when a non-default kernel name was entered. - Don't reset or forget the default drive/unit/... or kernel name so often. - Set the default kernel name to something unbootable after `?'. - Display the defaults better. - Removed PROBE_KEYBOARD_LOCK option (use -h instead)., - Removed BOOT_FORCE_COMCONSOLE option (use device flag 0x20 instead). - Removed -a (RB_HALT) flag. This flag is only used for reboots. Submitted by: about 2/3 by yokota

Usage: bios_drive:interface(unit,partition)kernel_name options
|
|
bios_drive 0, 1, ...
|
|
interface fd, wd or sd
|
|
unit 0, 1, ...
|
|
partition a, c, ...
|
|
kernel_name name of kernel, or ? for list of files in root directory
|
|
options -a (ask name) -C (cdrom) -c (userconfig) -D (dual consoles)
|
|
-d (debug early) -g (gdb) -h (serial console) -P (probe kbd)
|
|
-r (default root) -s (single user) -v (verbose)
|
|
Examples:
|
|
1:sd(0,a)mykernel boot `mykernel' on the first SCSI drive when one IDE
|
|
drive is present
|
|
1:wd(2,a) boot from the second (secondary master) IDE drive
|
|
1:sd(0,a)? list the files in the root directory on the specified
|
|
drive/unit/partition, and set the default bios_drive,
|
|
interface, unit and partition
|
|
-cv boot with the defaults, then run UserConfig to modify
|
|
hardware parameters (v), and print verbose messages (c)
