Mouse movement resets the system. (Miscellaneous) |
I changed my mouse from PS/2 to USB. When building a program by VP (Virtual Pascal) in dos, using HX dos extender, I move the mouse, the computer resets. What could be causing this? Some bug in UEFI/BIOS or in HX. When I used a PS/2 mouse it didn't happen. |

Did you check that the mouse works ok for real-mode programs? ---

The mouse works (except the wheel). I found that the problem occurs only in the configuration with the UMBPCI driver. |

Perhaps UMBPCI is a bit too "aggressive" and steals a range that's used by the BIOS's "USB legacy" code. UMBCHK might give further hints... ---

Apropos: Does anybody know, what happened to http://vpascal.ning.com/? ---

Allan Mertner told me today:
Hi Robert,
I'm not sure anyone uses it any longer; there is a Facebook group that has almost no traffic, but that's about it. Ning decided they wanted too much money for it to be worth keeping it there.
Cheers, Allan

The problem also occurs when I do not load the UMBPCI driver. Stack overflow is likely occurring on mouse movement. Same with M$DOS and FreeDOS. FreeDOS sometimes displays a memory block violation or invalid instruction execution message.
When I load one of the drivers (JEMM, QEMM or EMM386) this does not happen. In CONFIG.SYS I have set STACKS=9,256 |

That's a rather strong indication that it's NOT a real-mode stack overflow. ---

Seriously, the Ning to facebook move was quite a while ago, but there hasn't been much content there. |
