RE: LPC peripherals and LPC UART interrupts

your best bet is a filter driver on top of Microsoft's isapnp.sys

exactly how well you can do what you want to do will be dependent on a few
specifics

Hi,

Back again the the land of windows drivers... :)

Quick? question: if I have a custom device on the LPC bus that interfaces
a number of peripherals (including a couple of UARTS), then what type of
drivers do I need to write?

Do I need some sort of bus driver that enumerates these devices on LPC?

Also, I notice on the hardware I have here, there is a SuperIO chip on the
LPC bus. I also notice it has BIOS settings for the IRQs for the two
serial ports on it. I'm wondering how the interrupt steering works for
devices on the LPC bus as (AFAIK) there's only a single interrupt on
LPC?!? What am I missing here?

TIA
Regards,
Mark
