Hello, it's me again.

Has anyone had issues with the PS/2 mouse (with this modification) not working in Windows 98 but working without issues in DOS?

I don't think I have tested the PS/2 mouse mod in Win98, but every system I've used it in which contained Windows 95 has run beautifully. Normally I have to set the PS/2 rate to 80 Hz though, as the default for W95 (40 Hz, I think) isn't as smooth as I'd like it.

Tried to mod AOpen VI15G for PS2 mouse support. All unpopulated pads were there but after soldering everything, the boards locks up after couple of seconds after boot. Had to move some ferrite beads and resistors around. Even tried to swap the KBC but that didn't help. I wonder what I'm missing. Interestingly, when I turn the "Enable PS2 mouse" option in the BIOS to "false", the keyboard works fine, meaning the controller is properly set in PS2 mode and not in AT mode (as the connections for AT mode are severed after the mod).
Checked everything with my multimeter and all connections seem fine. Maybe some IRQ conflict but I don't have any peripheral installed apart from graphics card.
Has anyone here been successful with modding this board?

I've run 98 on a modded board, works fine
