Hello,

Sorry hackers, I have posted this to questions@freebsd, but got no
answer...

I did set my mainboard BIOS to use ECP transfer mode (dma 3 & irq 7). I
edited my kernel to:

device ppc0 at isa? flags 0x8 irq 7

(is there a way to declare the dma I want to use? config complains if I
add dma xyz)
and when I boot I get:

Jul  1 10:36:42 delta /kernel: ppc0: <Parallel port> at port
0x378-0x37f irq 7 flags 0x8 on isa0
Jul  1 10:36:42 delta /kernel: ppc0: Generic chipset (ECP-only) in ECP
mode
Jul  1 10:36:42 delta /kernel: ppc0: FIFO with 16/16/16 bytes threshold
Jul  1 10:36:42 delta /kernel: ppi0: <Parallel I/O> on ppbus0
Jul  1 10:36:42 delta /kernel: imm0: NIBBLE mode unavailable!

and my zip-100 drive does not get recognized. Is it possible to use vpo
in ECP mode?? EPP and compatible modes are just too damn slow.

thanks,

Paulo Roberto
