>Release: FreeBSD 2.2.6-RELEASE i386
>Environment:
2.2.6-RELEASE
>Description:
Large IDE drives are not supported by 2.2.6-RELEASE. Drives larger
than 8 GB can be utilized only up to 8 GB.
>How-To-Repeat:
Install a large IDE drive in a 2.2.6-RELEASE system.
>Fix:
Apply the following patch. It has been tested by several people. No
negative effects have been reported. This is a partial port of -current's
wd driver, only the LBA-relevant code has been merged. Note that, to use
this, flags need to be specified in the kernel configuration or userconfig
to switch a drive into LBA mode. The following configuration line works
for me (and our Quantum BigFoot 12G connected to the first IDE port):
controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xb0ffb0ff vector wdintr
Thanks to Soeren Schmidt for helping with the flags.
