Guys:


I remember a bunch of people PMing me about how slow the video display was in Bochs when running Rhapsody. For instance, the mouse was sticky and slow. Now, i have figured out a solution. Reduce the VGA refresh rate (or cycles) in the Rhapsody.bxrc file down to 1000. Observe the following text. This is extracted from the Rhapsody.bxrc file you are about to edit. You are gonna have to scroll down to see it.

#=======================================================================
# VGA_UPDATE_INTERVAL:
# Video memory is scanned for updates and screen updated every so many
# virtual seconds. The default is 40000, about 25Hz. Keep in mind that
# you must tweak the 'cpu: ips=N' directive to be as close to the number
# of emulated instructions-per-second your workstation can do, for this
# to be accurate.
#
# Examples:
# vga_update_interval: 250000
#=======================================================================
vga_update_interval: 18000

Change the value that is highlited in red to 18000 and you are set! Let me know if this doesn't work.

1000 is too fast, and it will kill the Processor speed.
You have to put the refresh around 60 Hz (your system monitor, in general), so, if 40000 is 25 Hz, then 20000 is 50 Hz... finally 60 Hz is around 18000.

Then you have to set the right amount of CPU's MIPS (Milion Instruction per second)... I have a 2.1 GHz Core 2 Duo and 20000000 is fine for me.
If you put a higher value, the processor will be stressed too much and will be slow, if you put a lower value then your cpu will not run as fast as it can be.
You have to try and find the right balance.

Hey Don... thank you so much for the input!
