PowerMac G4 and pcmcia flash cards

Hi,

need to write a little boot prom and I would like to use my G4 to put it
on a flash card. I have tried using pcmcia card services by David Hinds
and it won't even install. This is no surprise since he claims in the
HOWTO that Macs are not supproted yet. How you guys been using pcmcia
devices and does anyone know if I can do it on my G4?

Do you mean a binary installation?  Or were you trying to recompile?

It's not supported by him, but pcmcia-cs 3.0.14 should work on 2.2.x
kernels, especially if patched with the attached patchfile before
compiling.

Well, you're going to face a pretty fundamental barrier in that the
G4 does not have any PCMCIA sockets.  Despite appareances, the
internal AirPort socket on the AGP models is not PCMCIA.  It will not
work at all with anything other than an AirPort card.

For the basic services I can run he latest 3.1.11 package from David
with minor patching. It works well at least for Modems. A bit more
tweaking on the kernel side and I get CardBus services to run, e.g my
Xircom CBEM56G Modem/ethernet card. This is done on a Wallstreet I.
How about G4? I don't know, I suppose they don't have a PCI-TO-CARDBUS
bridge or even PCMCIA unless you add a card reader.

For the kernel patches, if you need them, they come later since I'm on work.

Actually, it smells a lot like a PCMCIA (not CardBus). It looks like a
kind of bastard of a PCMCIA and an IDE bus, and it's possible that some
PCMCIA card be made to work on it. I don't have enough infos for this yet
however.

It smells tantalizingly like PCMCIA because it's very close, but it
is deliberately broken so that it's not compatible with the regular
PCMCIA pinout.  This allows Apple to sell AirPort cards for $100 USD
without creating a gray market supply of cheap IEEE 802.11 cards,
which would undercut everyone else in the world who is selling the
same thing for $150-200.  When big companies cut special high volume
deals, ugly things happen.  :)
