sure it is ...
I'm surprised you get that much troubles. Can you tell us more about that weird platform ??
Have you walked along "OS tests" board and picked up disk images there to perform tests ? iirc, BlueIllusion and SolarOS have quite nicely-featured GUIs that might interrest you ...

Re:Mouse & Timing
The PC giving me the problem has the following specs:
ASUS A7N8X-Deluxe (nForce2 chipset)
AMD XP 2400+ CPU (@2GHz/33MHZ FSB)
Gainward GeForce4 Ti4800-SE AGP 8x
512MB DDR RAM
A Microsoft ergonomic keyboard, and an IntelliMouse Explorer optical, both connected via PS/2.
My friend with a similar motherboard had the same problem initially, but a small change to the bit testing in my if statement to see if data was ready fixed it for him. So I'm buggered if I know what's wrong with my system.
Just got myself another floppy drive, so I'm gonna make sure it works on my P-III still.
And I'll let you know how SolarOS runs on this quirky system of mine sometime tomorrow...

Just a thought that hit me as I read this.purevoid wrote: and an IntelliMouse Explorer optical, both connected via PS/2.
Are you using a PS/2 -> USB converter to attach that mouse?

Re:Mouse & Timing
Yeah, mouse has USB plug, and I use the converter thing to connect to PS/2 port.

He has a point there... that could be a problem, since it doesn't speak strict PS2 probably then.purevoid wrote: Yeah, mouse has USB plug, and I use the converter thing to connect to PS/2 port.

Re:Mouse & Timing
Hmm, fun problems for all.
I have a fairly whacked out theory (Difficult to diagnose from this far away). An Intellimouse draws a lot more power than an ordinary PS/2 mouse. Let's say that when the system is gets kinda loaded the voltage on the PS/2 port gets just irregular enough to reset the mouse. Can your driver handle getting an unexpected packet?
What's the rating of your PSU, and what do the core voltages look like? What happens with just an ordinary PS/2 mouse? Have you ever experienced the mouse freezing (Using the adaptor) when you've used something like Windows on that computer?
It's just a hunch, but is at least one thing you can test for fairly quickly.

It's a 300W PSU. And no, my mouse driver can't handle getting an unexpected packet. How are you supposed to tell it's an unexpected packet?

Re:Mouse & Timing
if i were you, i'd go to a store buy a 2? mouse and try it (well, it will even be useful if you're running out of batteries or whatever).
or ask a friend ...
I know that there are queries to be sent over a PS/2 wire to ask a mouse if it's wheel mouse or not. What i fear is that your intelleyexplorer mouse is actually believing it should send all sort of extra messages (including wheel movement reports or whatever) that the driver isn't ready to support ...
It is typical for wheelmice to move the cursor into a corner and start clicking deseperately once you tell the OS (e.g. linux) that it's a serial mouse or a logitech mouse or a normal PS2 mouse...

Re:Mouse & Timing
If it's one of those stylish nicely-designed microsoft mice with a red light at the bottom that I've used for a few times, I think it's a design / manufacturing flaw in the device. Didn't see one of them NOT doing it for more than a few hours. Test boxes include a bunch of P4's.
