NCL 537 IDE COntroller - source ?

[Joo T Goh]

Hi all,

I am looking for a particular IDE HD controller - a
NCL 537 made by NCL American Products Inc. This
particular controller allows you to change the IO
port to the secondary IO address as well as the
HD IRQ to 15. I needed both these features for
my LINUX box. Does anyone out there has a number
that i can call or suggest other cards with the
above 2 features?

Thank you in advance
Joo Thiam

Actually, you'd be surprised. I've found almost half of the super-cheap
generic type cards have a jumper for setting the I/O base address to the
original standard second address. (IBM, hobbling itself again, decided not
to support it in BIOS) I believe they also had alternate interrupts available.
(but that part is easy to modify :) They should work easily in your system. I
would be doing this now, but I ran out of slots. :/

Later,
Kevin

P.S. What I meant by "again", among other things, was in reference to IBM's
dumber-than-dumb decision to only support two drives on the MFM hard
drive controller. MFM specs call out four drive select lines...
