Ok, so I've got a great little Digital HiNote Ultra 2000, a 166 MHz Pentium
seat warmer. It has two builtin PCMCIA slots, plus space for two factory-
installed PCMCIA devices, an ethernet and a modem... of which this machine
only has a WinModem (groan). It also has a serial port, which I need, an
IRda port, and a sound system built in.
The PCMCIA slots are on pcic1, which wasn't too hard to figure out. I also
determined how to put pcic? into polling mode, to save on interrupts.
So, anyways, this system was already a bit stressed for IRQ's.
3 is serial, 4 is IRda, 5 is sound card, 7 is lpt, pcic-pci{0,1,2,3} soak
up 9 and 10, 11 I use for PCMCIA, 12 is psm, I don't know if it is OK to
use 13, 14 is HDD, and 15 is multimedia dock.
And now I've this nifty multimedia dock which actually lets me hear the
audio :-) but at the same time it introduces additional complexity, as it
has two additional PCMCIA slots, a USB port, an additional slot for a
floppy or CDROM, etc..
First, where might I find this *THIRD* PCMCIA controller (presumably pcic2)
Second, what the hell do people do to have all their stuff work and yet work
around the limited number of irq's?
Thanks :-)
