Win2K vs Win98 IRQs

[Guest]

Is there a difference in how Win98 and Win2K programically use IRQ's and/or the realtime clock?

The context of my questions:

I have a developer telling me that an application wrote for win98 will be quite an effort to migrate to Win2K because Win2K doesn't have the same interupts available as was in Win98.

This is somewhat confusing to me because I always thought this was handled at a processor/BIOS level.

Can anyone offer any clarification?

Thanks,

Todd

Better to ask in a developer NG.

W2k is a shared IRQ environment, and yes it has the same
IRQ as 98, it just shares, however it does deal with
hardware communication at a different level.
98 allowed software to speak directly to the hardware,
W2k says you must go thru the HAL to get to the hardware.
so some 98 programs may not work with W2k.
You might try running them in compatable mode.
