Hmm. seabios uses pmtimer if available. isapc has no pmtimer though, so it uses TSC instead. > So we should use '-cpu Conroe' or '-cpu core2duo' minimum? -cpu Conroe for -M isapc is kida silly though ... Maybe we should simply build seabios with CONFIG_TSC_TIMER=n ? Using the TSC in a virtual machine is problematic anyway, the calibration can be _way_ off on a loaded host, this is why seabios prefers the (fixed frequency) pmtimer. cheers, Gerd _______________________________________________ SeaBIOS mailing list -- seabios@seabios.org To unsubscribe send an email to seabios-le...@seabios.org
