- Well, first of all, you didn't have to go through all those different
- installations -- just do a "mkdev mouse" once the system is installed
- to reconfigure the mouse.
-
- And no, the Mouseman is not a keyboard mouse. It is either a
- Microsoft-compatible bus mouse or a "new-style" Logitech bus mouse,
- depending on which driver you configure. ODT 2.0 should have drivers
- for both.
-
- As for interrupt 2 -- yes, it can be a bit flakey if you have an older
- VGA card. The EGA used IRQ 2 for the vertical retrace interrupt, and
- older VGA cards frequently implemented this for compatibility reasons.
- Newer cards either have it disabled, or have a jumper to select
- the behavior, because few (no?) programs depend on it anymore. Your
- best bet would be to move the bus mouse to IRQ 5 or some other unused
- interrupt and try it again.
