- Announcing the sixth update to MkLinux DR2.1.
-
- This is the one that many of you have been waiting for! This update has
- improved serial support on both the NuBus and PCI class machines. Yes,
- you can now run PPP reliably on the PCI machines. In addition, a few other
- bugs were fixed, and a few new features are included.
-
- The update is available for anonymous ftp from ftp.mklinux.apple.com:
-
- ftp://ftp.mklinux.apple.com/pub/Updates/DR2.1update6/
-
- or our various mirror sites, in the directory:
-
- .../Updates/DR2.1update6/
-
- (Please be patient with the mirror sites, it may take them some time to
- mirror the update)
-
- *** IMPORTANT NOTES ****
-
- General
- -------
-
- This update consists of a new Microkernel, Linux Server and Default Pager.
- The MkLinux Booter doesn't need to change between the previous update
- (DR2.1update5) and this update (DR2.1update6). However, if you are updating
- from an update earlier than DR2.1update5, then you will need to obtain the
- MkLinux Booter from update5. Pay particular attention to the README.install
- when skipping updates.
-
- There are no new RPMs (Redhat Package Manager) packages to download and
- install. As with update 5, there have been newer versions of some of
- the shared library based RPMs made available since update 4, as well as
- many shared library based RPMs that weren't part of updates 3 and 4.
- However, they are not part of this update. You may obtain them separately
- from ftp.linuxppc.org and its mirrors.
-
- The sources to the Microkernel, Default Pager, and Linux Server, as well
- as the tools and instructions needed to build them, are included for those
- of you interested. However, there is no requirement to rebuild these
- components in order to apply the update.
-
-
- Upgrade Path
- ------------
-
- This is an update to MkLinux DR2.1. If you are still running MkLinux DR1,
- DR2, or DR2 with updates, then you should upgrade to DR2.1 before applying
- this update.
-
- It is easiest if you apply this update to a system that has already been
- updated to the previous level, DR2.1update5. However, it is possible
- to skip updates if you follow the instructions in the file README.install.
-
- Here's a summary:
-
- From: To: Valid:
- ----- --- ------
- DR2.1update5 -> DR2.1update6 (YES)
- DR2.1update4 -> DR2.1update6 (YES) *
- DR2.1update3 -> DR2.1update6 (YES) *
- DR2.1update2 -> DR2.1update6 (YES) *
- DR2.1update1 -> DR2.1update6 (YES) *
- DR2.1 -> DR2.1update6 (YES) *
- DR2 -> DR2.1update6 (NO)
- DR1 -> DR2.1update6 (NO)
-
- * Note: When updating a DR2.1, DR2.1update1, DR2.1update2, DR2.1update3,
- or DR2.1update4 system to this update (DR2.1update6), you will need to
- apply the pieces from this update (the kernel, server, default pager), the
- booter from DR2.1update5, and then bring the shared libraries on your system
- up to the "DR2.1update4" level (if they aren't already). See the file
- README.install for more information.
-
-
- Bug Fixes
- ---------
- We believe this update fixes the following bugs.
-
- - The serial driver has been improved significantly. It can now support
- PPP at speeds up to 230.4k baud, even on PCI machines.
-
- - Fixed major number of /dev/adb device
-
- - Server doesn't crash anymore when using pdisk on 2Gig drives and larger.
-
-
- Enhancements
- ------------
-
- - Initial work to determine whether your Mac is "I/O coherent" or not.
- This affects cache behavior, and is needed in device drivers which
- are shared between I/O coherent, and non-I/O coherent machines.
-
- - More support for various 3 button mice.
-
- - Better support for /proc/stat cpu info, allowing display meters such as
- xsysinfo to display current cpu usage (in addition to load averages).
-
- - Support for per-process CPU-usage limits (see man bash, ulimit -t).
-
- - Audio support for older NuBus machines (play only).
-
-
- Known Problems
- --------------
-
- - The MkLinux Booter from update5 was built improperly and doesn't fail
- properly when it cannot find the Mach Kernel. If you are getting "Type
- 12" errors, address errors, or other MacOS crashes when you attempt to
- boot MkLinux, you might want to double-check that you've got your new
- Mach Kernel named exactly "Mach Kernel" (with the space, _not_ an
- underscore). If that still doesn't help you, there is a version of the
- MkLinux Booter that was rebuilt to fail properly, and give you a more
- descriptive message.
- See ftp://ftp.mklinux.apple.com/pub/wip/booter/README for details.
-
- - The audio on the NuBus machines sounds a little "scratchy".
-
- - As we try to figure out and support all the third-party three-button
- ADB mice out there, occasionally some will stop working when they had
- worked in previous updates. That may be the case with this update.
- As these problems come in, we'll try to refine the ADB handling to
- reliably handle all the third-party mice. If the second and third
- buttons on your mouse stop working with this update, remember that
- you can emulate these buttons by pressing option-2 and option-3 on
- the keyboard.
