This may not be the correct forum to post this topic- but I don't know where it should go.
I was trying to find information about IRQ priorities on the cascading of the 8259 chips.
Information I found on the priorities was not consistent - regarding where IRQ 8 fell.

I have 3 diffrent descriptions of the priorities.

******
0, 1
2/9
10-15
3-7
8

******
0, 1
2/9
8
10-15
3-7

******
0, 1
2/9
10-15
8
3-7
******

Can anyone tell me where I can find an article that will have accurate information on the priorities?

Thanks, Fay
