ArcaOS CONFIG.SYS Tips

This page contains an actual CONFIG.SYS from an ArcaOS system with comments on some of the changes that can be made to increase performance.

PSD=ACPI.PSD
BASEDEV=IBMKBD.SYS
BASEDEV=TIMER0.SYS
BASEDEV=PRINT01.SYS

If you don't have a paralell port or don't use a parallel port printer remove the PRINT01.SYS line.

BASEDEV=CHKDSK.SYS
BASEDEV=USBD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBUHCD.SYS
BASEDEV=USBEHCD.SYS
BASEDEV=USBHID.SYS
BASEDEV=USBKBD.SYS
BaseDev=CADH.SYS
BASEDEV=APM.ADD

If you don't have any apps that need APM emulation remove the APM.ADD line.

BASEDEV=DANIS506.ADD /!BIOS

If you don't use any IDE/S506 disk drives, you can remove the DANIS506.ADD line.

BASEDEV=IBM1FLPY.ADD

If you don't use floppies or if you don't have any floppy drives, you can remove the IBM1FLPY.ADD line.

BASEDEV=USBCDROM.ADD /CDS:1

Always remove this line. If you need to use a USB CD/DVD drive, just add the /CDS:1 switch to the USBMSD line.

BASEDEV=USBMSD.ADD /REMOVABLES:8 /FLOPPIES:0

The default for /REMOVABLES is 4, and the default for /FLOPPIES is zero. So unless you actually need to connect more than 4 USB sticks at the same time you can remove both of these switches.

BASEDEV=DANIATAP.FLT
BASEDEV=OS2DASD.DMD
BASEDEV=OS2LVM.DMD
BASEDEV=OS2ASPI.DMD /ALL

This enables caching for FAT32 disks. If you don't use FAT32 disks or don't need the caching you can remove the CACHEF32.EXE line.

The LVMALERT.EXE is unnecessary for normal ArcaOS users.

The EXTENDFS.EXE is unnecessary for normal ArcaOS users who don't use spanned volumes.
