Hello.
In James Molloy's tutorial, the IRQ handler function calls outb(0xA0, 0x20); and later outb(0x20, 0x20);.
Could anyone please link to a list of ports, that I could use to macro those magic numbers into something understandable?
Thank you.
Is there a "standard" ports list?
Re: Is there a "standard" ports list?
At the top of the forum you find a link labeled "The OSDev.org Wiki - Got a question? Search this first!".
Searching that for "Ports" yields:
I/O Ports
Where Can I Find Information About Ports
Port IO
Bottom line: No such thing - for a reason.

Every good solution is obvious once you've found it.
