Ok - What interrupts are your isa cards supposed to use? On the Noname all
PCI interrupts are routed through the isa-bridge. As a consequence not all
interrupts are available to ISA devices. And this routing is currently
hardwired. I currently use the following patch to get the IRQ-routing
right for me (I don't use ide but I need irq 15 for an extra serial card):

ALIAS_MV(noname)
This value assigns each of the 4 PCI interrupts the wanted IRQ-number. Thus my
replacement uses INT11 (=0x0b) for one PCI interrupt (happens to be the
onboard scsi controller) and INT14 (=0x0e) for the other PCI interrupts (i.e.
they are shared!).
The original value is just wrong because INT13 (=0x0d) can't be used at all
(ugh, Intel math coprocessor stuff :-/) That may well explain why your 3c905
doesn't work - it picked INT13. Swap it to another slot and that other card
will fail....

No. The kernel does that itself.

Count the jumpers - they are all explained in your docs :-) i.e. No write-
protect jumper.
I had no problems (apart from learning booting basics for alpha :-)) putting
MILO into flash.
