boot serial console speed
what's the magic encantation to set the console to 38400? btw, i solved my problem by just commenting out that part of the code, since i rely on the bios setting it. from src/sys/boot/i386/boot0/Makefile: # Comm settings for boot0sio. 0xE3 = 9600 8-N-1 # XXX: We should create a build-tool or something to convert BOOT_CONSOLE_SPEED # and BOOT_COMCONSOLE_PORT into the correct values to define on the build # command line BOOT_BOOT0_COMCONSOLE_SPEED?= 0xE3 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

btw, i solved my problem by just commenting out that part of the code,
since i rely on the bios setting it.
from src/sys/boot/i386/boot0/Makefile:
# Comm settings for boot0sio. 0xE3 = 9600 8-N-1
# XXX: We should create a build-tool or something to convert
BOOT_CONSOLE_SPEED
# and BOOT_COMCONSOLE_PORT into the correct values to define on the build
# command line
BOOT_BOOT0_COMCONSOLE_SPEED?= 0xE3
This is the value passed in the AL register to the Int 14/AH=00h
BIOS function:
http://www.ctyme.com/intr/rb-0811.htm
: Bit(s) Description (Table 00300)
: 7-5data rate (110,150,300,600,1200,2400,4800,9600 bps)
: 4-3parity (00 or 10 = none, 01 = odd, 11 = even)
: 2 stop bits (set = 2, clear = 1)
: 1-0data bits (00 = 5, 01 = 6, 10 = 7, 11 = 8)
0xE3 = 111-00-0-11 = 9600 bps, no parity, 1 stop bit, 8 data bits
But I think it's not possible to set it to anything above 9600 bps
using this BIOS call.
Attached is the patch that converts supported BOOT_COMCONSOLE_SPEED
values into corresponding BOOT_BOOT0_COMCONSOLE_SPEED. Unsupported
BOOT_COMCONSOLE_VALUES cause the boot0sio console speed to be set
to 9600.
Cheers,

Re: Mysql - Linuxthreads : Still needed?
This is unfortunate, since 4.1.7 is the recommended release from MySQL AB. Does anyone know why 4.0 is faster, or is it only faster in some cases (anybody have any benchmarks?) ? 50% is quite a large margin and I'm sure most people, myself included, are looking for maximum performance. I cant repeat my tests to show you topically benchmark results at the moment. But why dont you find out how it performance in your own conditions and then share your experiences with us? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
