Hi, long story short:
boot0cfg -B ad0 -> No beeping on boot
boot0cfg -B -o noupdate ad0 -> Annoying beep.
I really don't know any assembler, but reading
/sys/boot/i386/boot0/boot0.S leads me to believe that there should be a
beep on every boot. However, I certainly don't want any beeps from
boot0, can I comment out the first two lines of main.10?
/*
* 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
int $0x1a # system time
movw %dx,%di # Ticks when
addw _TICKS(%bp),%di # timeout
/*
* Busy loop, looking for keystrokes but keeping one eye on the time.
*/
main.8:
#ifndef SIO
movb $0x1,%ah # BIOS: Check
int $0x16 # for keypress
jnz main.11 # Have one
#else /* SIO */
movb $0x03,%ah # BIOS: Read COM
call bioscom
testb $0x01,%ah # Check line status
jnz main.11 # (bit 1 indicates input)
#endif /* SIO */
xorb %ah,%ah # BIOS: Get
int $0x1a # system time
cmpw %di,%dx # Timeout?
jb main.8 # No
