There have been many, many Alpha-specific enchancements since the
|
|
1.3 release. These include:
|
|
.Bl -bullet

Many new system types are supported:

|
Jason Thorpe's new virtual memory code provides
|
|
full support for the alpha's large address space with context switching
|
|
and translation buffer state optimizations.
|
|
.It
|
|
Extensive scheduler work enables process nice levels to work as expected,
|
|
fixing ancient BSD scheduler bugs that affected NetBSD/alpha more than
|
|
other ports with slower clock Hz defaults. Nice +19 and +20 processes
|
|
now take no time away from nice +0 programs regardless of load average.
|
|
.It
|
|
Many new device drivers and sound cards are supported. Floppy
|
|
disk drives are now supported.
|
|
.It
|
|
IDE peripheral devices are now supported on Multia and AXPPCI33 systems.
|
|
.It
|
|
A new multi-volume boot loader allows all supported system types
|
|
and device drivers to be present on floppy disk media, and enables the
|
|
.Em sysinst
|
|
screen-menu installation program to be included on
|
|
floppy disks as well. Although two floppies are now used, they load
|
|
much faster than the single floppy did in 1.3.
|
|
.It
|
|
Installation from CD and magnetic tape media is now supported.
|
|
.It
|
|
A new set of boot programs provides considerable operational and
|
|
performance enhancement.

|
|
NetBSD \*V on alpha is, as usual, also fully backward compatible
|
|
with old NetBSD/alpha binaries, so you don't need to recompile all
|
|
your local programs.
