LS/VS550 OWNER’S HANDBOOK 6/5
Any parallel port devices that you may wish to attach, such as a tape
streamer or external hard drive etc., should have full instructions
supplied with them that will tell you if the port capabilities need to
be manually altered to one of the extended options listed.
Mouse
This option enables the use of a mouse. The actual presence of the
mouse can then be detected by POST. You should not normally
disable this setting.
Diskette Controller
This option enables the use of the 3.5” floppy diskette drive. You
should not normally disable this setting.
Floppy disk drives
This lets you specify what diskette and floppy disk drives are fitted.
Diskette drive A which is fitted by default, is invariably a 1.44
Mbytes 3.5” drive. You will not be required to change this setting.
Video Setup
If selected this opens a screen which details the video controller and
the size of the video memory.
IDE Controller
This must be ‘enabled’ if the system is supplied with an IDE CD-
ROM, but may be disabled if all drives are exclusively SCSI.
IDE Drives Setup
The motherboard has two IDE/ATA (Integrated Drive electronics
AT-Attachment) interfaces, supporting two drives on each.
However, the computer itself can accommodate only two IDE hard
disk drives, on the primary interface, so any removable-media
drives, typically a CD-ROM drive, should be connected to the
secondary interface.
