freebsd kernel with SKQ

affects cases where there is a slave but no master. These bugs were usually recovered from provided ATAPI was configured, but only after lengthy delays. Configuring ATAPI still fixes some bugs for non-atapi drives. Don't wait for seek complete in wdreset(). If necessary for pre-ata drives, it can be waited for later (we got it wrong by only looking at it for drive 0 anyway). It is set as part of a historical signature for ata drives but doesn't say anything useful about the reset state. It is cleared as part of a non-historical signature for atapi drives so that drivers which don't understand atapi drives seem to see no drive. Waiting for it caused lengthy delays and broke the status returned by wdreset() in cases where the master was not an ata drive. Then the whole wdprobe() failed in some cases where the recovery code didn't work. Don't wait for drive ready in wdreset(). The considerations are the same as for seek complete, except drive ready does say something useful about the reset state of ata drives, and waiting for it later is required anyway for such drives. Lengthy delays can now be avoided by not configuring nonexistent (ata) drives. Unfortunately, this breaks detection of atapi drives in some configurations. |

UPDATING |
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
