No new Linux distros are shipping 2.4 kernels anymore... Well, I down loaded and installed RedHat-9 5 weeks ago, and it is a 2.4 kernel, so I thought that would be fine.

This is a driver for talking to my hardware which is a PCI bus card. This card has 5 large FPGAs, SRAM and dram on it which is used to accelerate bioinformatics search algorithms. The card works under Sun Solaris and Windows/2000, and of course, we would like to add Linux to the list. Eventually, I'll need to support DMA to and from the card, but I can get by for a while just doing single-dword I/O. I just hacked in dev->bus->ops->read_dword(dev,1,&retval); and I can read memory on the card! (Well, things don't crash anyway) If this is absolutely the wrong way to do this, please let me know! Note: I have no idea what the second parameter to read_dword() is! -Alan -- - Alan Kilian Director of Bioinformatics, TimeLogic Corporation 763-449-7622
