It is said that the original Win98 has some problems in the USB 
stack and class drivers. Win98 SE fixed them. Then again WinXP
fixed lots of the problems of Win9x and are actually quite
good even on lower spec PCs. I've used WinXP on a P3 450 PC
which ran much faster than Redhat 9 Linux.

For example, the HID class driver is different. Win98 original
supports only HID 1.0. Win98 SE supports HID 1.1 which adds 
the ability to do interrupt OUT transfers. 

PICkit 1/2 will not work under original Win98 but they will
work under Win98 SE since they need HID 1.1.

Subject: Re: [PIC] When did MPLAB stop supporting Win98?

But back to the original subject, it sounds like the new MPLAB works on
98SE but not 98. What are the real differences between the versions?

Cheers,

Bob
