--MGYHOYXEY6WxJCY8 Content-Type: text/plain; charset=iso-8859-15 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable 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 Ulrich Sp=F6rlein --=20 PGP Key ID: F0DB9F44 Encrypted mail welcome!
