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. ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
