We looking at the same man pages? You don't say if you're running 2.0.5, but if you are, your problem is straightforward.

I don't recall the flags off the top of my head, but I'm sending you my How-To sheet in another message (this list has now seen it once and it's slated for the handbook, so I don't want to waste everyone's storage space.

No, same flag for all 16. It's really irrelevant - from the man sio page: flags 0xb05 means that the 12th port (sio11) is the master port, and that the port is on a multiport card with shared IRQs and no special IRQ con- trol register. Which port is the master port depends on the card type. Consult the hardware documentation of your card. Since IRQ status registers are nev- er used, and IRQ control registers are only used for AST/4 compatible cards, and some cards map the control/status registers to all ports in a group, any port in a group will sometimes do for the master port. Choose a port containing an IRQ status register for forwards compatibility, and the highest possible port for consistency. **** The since the Boca doesn't use an AST compatible setup, it's really irrelevant. In fact, my current kernel config is incorrect, pointing at the second port of my Boca, and it works fine. The man page suggests you set it to the last port for consistancy. Seems unlikely you're gonna get an sio update with the same kernel, but who knows... The 05 part of the flags are definately correct, however. > This system is running an old snapshot from early February (with a couple > of patches to fix crashes). Has sio improved any in 2.0.5?

Well, unless the sio driver changed from the feb snap to the april snap, they're the same.
