+Status:
+ BETA-RELEASE
This driver is currently developped under the following O/S:
FreeBSD 4.0 SNAPSHOT July 5th 1999
+ FreeBSD 4.0 current October 1999
Starting with version 0.9.0, the driver contains conditionnal code
for using pre-4.0 BUS stuff for PCI. I have successfully tested driver
version 0.9.0 under:
FreeBSD 3.2 RELEASE
- Given that the old bus stuff is still supported under FreeBSD, the driver
- should also compile and work just fine under FreeBSD 3.3 RELEASE.
