I revived an old PC with a 430tx chipset (QDI Titanium IB mainboard). Since
it did not have a PS/2 connector i added a USB card and a USB mouse. The
mouse works fine with a normal boot. However, when I go into safe mode the
mouse doesn't work at all. During the boot into safe mode i get the message
that there is no mouse on a PS/2 port and I can connect a serial mouse if I
want.

is this normal or have i done something wrong? There are no unknown devices
in device manager and all USB drivers loaded properly and the USB hubs are
listed normally.

thanks,

rich c

Safe mode does not load any drivers (i.e. drivers for your USB card). I'm
not sure, but you might be able to purchase a cheap USB to Serial adaptor
for the mouse. Although it might be a bit hard to find. Speculation, of
course. If there are none available, you could always get a PS/2 mouse with
a PS/2 to serial adaptor.

These don't exist.

Only works if the mouse is a "universal" mouse, ie has both the serial and
PS2 circuitry in the mouse to handle both protocols.

Safemode in win9X doesn't load 32 bit drivers so in effect it uses 16
bit Dos drivers.If your mother board doesn't have USB legacy dos
support and your mouse doesn't have USB dos drivers then you can't
have the mouse in safemode or dos.
However you could use a cheap serial mouse for Safemode or
use the keyboard to navigate.It's not so hard once learnt using the
Tab/Alt/Cursor/Enter keys and the windows logo key.
There are also lots of key combo shortcuts like The windows key+pause
key to get to the System settings.

There are some,"Power users" who refuse to use a mouse and can
operate way faster on just a keyboard for most operations.
HTH :)

When you go into Safemode, Windows only loads the MINIMAL drivers needed to
boot. USB drivers for the USB card are not included.

I thought most new usb mice came with such adapters, at least the
logitech ones which I have dealt with in the past did.

The come with the USB to PS/2 adaptor. Not the USB/PS2 to serial adaptor.
You are living in 1997? :)

Never seen a USB to serial adapter (which is what was asked for
originally). Current Logitech optical mice only support USB and PS2. Also,
not all USB mice (mouses?-) work with adapters. Have only seen USB to PS2
on mice that support it out of the box.

There is no such thing as a Generic PS2 to Serial adapter. The mouse has to
support it. Most manufactures consider the serial mouse obsolete and don't
support it any more.

Look for a set of header pins labelled JP1, right next to the keyboard
socket, on the side opposite the header pins for the USB ports.
You'll need a cable that plugs into the JP1 pins and goes to a PS/2
socket, but they are available, usually with the PS/2 socket on a rear
chassis bracket. However they're not all wired the same, and I
believe that QDI uses

1. data
2. clock
3. ground
4. empty
5. +5V

The other style, used by FIC and some others, has:

1. data
2. empty
3. ground
4. +5V
5. clock

Carefully identify pin #1 because it tells you which style you have.
If you see a thin copper trace going to a pin, it's almost always for
either clock or data. You can rearrange a socket hole if needed by
pressing on its locking tab on the side of and pulling it out. Some
socket bodies have a plastic cover over each pin that has to be pried
up with a jeweler's screwdriver.

To what? You can get serial to USB adaptors, but those are smart
devices, and equate to a serial port on the system. The USB to PS2
adaptopr is simply an electrical pin adaptor, the USB mouse or
keyboard have to be able to "speak" PS2 on it's plug.
IOW, that, or no plug in adaptor, converts the USB data to PS2,
or serial>PS2, or PS2>serial.
