If you update FreeDOS, in accordance with the update list
noted by Eric Auer, do consider adding the UIDE or UIDEJR
driver, also XMGR and RDISK if desired.   They are avail-
able from <http://johnson.tmfc.net/dos/driver.html>, also
 from other Internet sources.

UIDEJR is a "basic" hard-disk and CD/DVD driver.   It can
run SATA or IDE disk/CD/DVD drives, in many cases about 2
times as fast as BIOS logic for disks or older "PIO mode"
drivers for CD/DVD drives.    UIDEJR replaces the GCDROM,
XCDROM, and XDMA drivers, offering faster performance via
use of an XMS buffer for I-O "not suited" to UltraDMA.

UIDE adds caching for disk/diskette/CD/DVD drives and has
the same device-handler capability as UIDEJR.   Its cache
makes UIDE about 2 times faster than UIDEJR for both disk
and CD/DVD drives.   UIDE can cache 5-MB to 2-GB of data!

UIDE/UIDEJR take about 5K/3K of upper-memory on a FreeDOS
system, that does not provide HMA space to drivers loaded
by the CONFIG.SYS file.   If desired, Eric Auer's DEVLOAD
can be used to load them from the AUTOEXEC.BAT file, thus
reducing UIDE/UIDEJR to 992/768 bytes of upper-memory and
the rest occupying HMA space.

JEMM386 is recommended for extra upper-memory, DPMI/VCPI,
or if any "protected mode" applications are used.    If a
simple "real mode" system is wanted, the UMBPCI driver by
Uwe Sieber and the XMGR driver (offered with UIDE) can be
used.   XMGR has built-in features to support the "Shadow
RAM" memory used by UMBPCI, which does not allow DMA.

See the README file for XMGR/RDISK/UIDE for some examples
of CONFIG.SYS files that can load these drivers.
