Boot manager beep

[Thomas E. Zander]

Hi,

just installed a fresh 6.0 on a laptop, using the standard boot
manager. The problem is: The default volume of pcspeaker can't be tuned
in bios or anywhere else before loading a sound driver (in this case
snd_ich). This especially means the pc speaker volume is always set to
100% at every boot which results in a horribly loud beep which I am
afraid the built-in "speakers" can't do very often :-)

So what about this one:

--- /usr/src/sys/boot/i386/boot0/boot0.S
+++ boot0.S
@@ -201,9 +201,7 @@
 /*
  * Start of input loop.  Beep and take note of time
  */
-main.10:	movb $ASCII_BEL,%al		# Signal
-		callw putchr			#  beep!
-		xorb %ah,%ah			# BIOS: Get
+main.10:	xorb %ah,%ah			# BIOS: Get
 		int $0x1a			#  system time
 		movw %dx,%di			# Ticks when
 		addw _TICKS(%bp),%di		#  timeout

This might be an issue on other architectures (amd64?) as well, I
haven't checked that right now.

TIA,
Riggs
