If there are Linux drivers for it, you're half way there, but there is one other factor - OpenBoot
I've just tried to put a RICOH based CardBus/PCMCIA bridge card into my E4500's 3.3V PCI slot (PCI I/O board) and while I know that Linux can drive this chip, OBP chokes when probing the card and throws a "Data Access Error" before dropping me to the ok prompt. I tried booting anyway, and it just hung .)
If anyone knows how to avoid probing certain PCI slots through OBP/nvramrc etc. that would be useful to know. On the UPA/PCI systems there is a pci-probe-list or pci-slot-skip-list variable, but on this old hulk there are only SBus-related variables in the printenv list.
Sorry to follow up a question with a new question but it seems highly relevant in this case; to the poster - maybe you can try the board first and then take it back if it doesn't like it. |

Assuming there is a working kernel driver for it, maybe. It depends on how well the driver was written.
Even if the driver is detected correctly, there may not be the right 32 to 64 bit ioctl conversions to support the userland tools you want to use.
For instance, I recently tried setting up an older 802.11g USB wireless NIC on my Blade 1000. The Prism54 USB driver was able to pick it up and some of the tools from the wireless-tools package were able to poll it for information, but kismet was not able to work with it. I haven't actually attempted to associate it with an access point or anything like that. |
