 + The BIOS expects memory refresh to occur roughly every 16us, which I've resolved by tying the state
-of the refresh bit in port 0x61 to bit 6 of the CPU cycle count (see *in8042RWReg()* in [chipset.js](/modules/pcx86/lib/chipset.js));
-the original AT BIOS was satisfied with a refresh bit that merely alternated, whereas the new AT BIOS

+  when the keyboard's "clock" line is toggled (see *set8042CmdData()* in [chipset.js](/modules/pcx86/lib/chipset.js)).

-the BIOS probes for a second hard drive anyway, and it does so by simply writing the drive number to the ATC's

-that must immediately update the "STATUS" register.

 A new PCx86 Control Panel is under development, featuring a new "Display Panel" that will provide a variety of
 information about the machine, in real-time, and operate more efficiently than previous DOM-based Control Panels.
 
 A preview of the layout is shown below.  There's not much to see yet, as this is very much a work-in-progress.
