@ -11,20 +11,20 @@ Exciting news for OS/2 fans: PCjs (v1.16.1) is now able to run OS/2 1.0 on
of recent work in PCjs to fully emulate the Intel 80286 processor and 16-bit protected-mode, including undocumented
features like [LOADALL](/pubs/pc/reference/intel/80286/loadall/) and triple-fault resets.
For a quick demo, try the "[OS/2 1.0 Debugger Boot Disk](/disks/pc/os2/misc/)". In a few seconds,
For a quick demo, try the [OS/2 1.0 Debugger Boot Disk](/disks/pc/os2/misc/1.0/debugger/). In a few seconds,
you'll see a very rudimentary OS/2 shell (a slimmed-down version of the OS/2 Program Selector) that allows you to
start the protected-mode command interpreter ("Start a Program") or the real-mode command interpreter ("command.com").

As an added bonus, the Model 5170 machines feature two serial ports, with COM1 connected to a simulated serial
mouse and COM2 connected to the **Control Panel** output window.
Once you've booted the "OS/2 1.0 Debugger Boot Disk" from the assortment of [OS/2 Miscellaneous Disks](/disks/pc/os2/misc/),
you can click on the **Control Panel** output window, press Ctrl-C, and find yourself magically transported
into the OS/2 Kernel Debugger. The **Control Panel** display is functioning as both the output window for all PCjs
messages and PCjs Debugger commands, as well as a serial input/output device (aka "Dumb Terminal") for any software
inside the machine communicating via COM2: in this case, the OS/2 Kernel Debugger.

> SIDEBAR: You can perform similar tricks with DOS in these machines. Boot any DOS disk (version 2.00 and up)
and type "CTTY COM2" at the DOS prompt. All DOS input/output will now be routed to the **Control Panel** display.
