Default Analog Joystick Mystery

Hi,

I have a Compaq Presario 1060 laptop (WIN95), bought around 1997. It has a
game port connector. I have two analog joysticks (Kraft and Quick Shot,
QS201) which I am unable to use in Dos mode (Windows shut down). I can use
them at the Dos "Prompt". I couldn't find a Dos mode driver for either
joystick, but there is a handler in BIOS for a joystick so I really don't need
a Dos driver.

I used a Dos based "JOYREAD" tool which uses two modes (the joystick
handler in BIOS or software loop) to read the joystick port (0201h). Both
modes work fine at the Dos "Prompt", but neither works in Dos mode. Simple
button/s pressing can't be detected in Dos mode, but detected just fine at Dos
Prompt!!!

Note: I have a Dos mode Commodore 64 emulator that will not "run"
at the Dos prompt. I have many C64 games that work best with a
joystick. Also note, I have a Compaq Presario CDS774 desktop
computer I bought in late 1995. These same joysticks work just
fine in Dos mode (without Windows) using the BIOS joystick handler.

Is there a direct connection with the sound system (ES1788 from
ESS Technology) and this port?

What "enables" this port when Windows is launched, even though
there is a BIOS (rom) handler for this port?

Thanks in advance, Brad
