i386-specific enhancements include a number of new device drivers, such
as the Intel Etherexpress FE drivers, ATAPI support, and others.
See the hardware compatibility list for supported devices.
As is usual between releases, the i386 port has had many improvements
made to it -- too many to detail all of them here.

Numerous new drivers have been added. See the supported hardware list
for details.

APM support
Lennart Augustsson has added full USB support, permitting the use of a
wide variety of Universal Serial Bus peripherals.
.It
bounce-buffer support so that busmaster ISA controllers work
for machines with \*> 16MB
Manuel Bouyer's PCIIDE work now permits full DMA support on IDE
controller/drive combinations that support it. This dramatically
improves performance on supported hardware.
.It
floppy formatting support
New i386 boot blocks now support INT13 extensions. This means that on
modern BIOSes, it is possible to boot a NetBSD partition that is past
the old 1024 cylinder boundary. The new boot blocks also support a
mechanism to pass BIOS geometry information to the kernel, permitting
improved automation during installs.

improved detection of the amount of memory present in the machine

support for FAT32 filesystems
The i386 port also now uses libkvm -- libkvm.old has finally been purged.

provided you set the appropriate binary compatibility options in your
kernel configuration.

The i386 will be switching executable formats from a.out to ELF in
the next release. The support for this has already been completed, but
was judged too new to be included in
.Nx 1.4 .
