Display.sys

Enables the display of international character sets.

Syntax

The Display.sys device driver must be loaded in Config.sys using either a Device or DeviceHigh statement in one of the following formats:

Device/DeviceHigh = [Path]Display.sys CON=(type)

Device/DeviceHigh = [Path]Display.sys CON=(type,hwcp)

Device/DeviceHigh = [Path]Display.sys CON=(type,hwcp,n)

Device/DeviceHigh = [Path]Display.sys CON=(type,hwcp,(n,m))

Path	The full path. Default is the root directory of the start-up drive (usually C:/)
type	Specifies the display adapter in use (see table below). If type is omitted, DISPLAY.SYS checks the hardware to determine which display adapter is in use.
hwcp	Specifies the number of the Code Page (character set) hard coded in the display adaptor. If this parameter is included, it is always possible to switch back to it whichever Code Page is specified using the MODE and CHCP commands Character sets and associated languages United States English 437 Multilingual (Latin 1) 850 Canadian French 865 Slavic (Latin 2) 852 Portuguese 860 Nordic 865
n	Specifies the number of character sets the hardware can support in addition to the primary character set specified for the hwcp parameter.
m	Specifies the number of subfonts the hardware supports for each code page.

Valid values of type, m and n

Display Adaptor	type	n	m
EGA, VGA, or SVGA	EGA	0 to 6	2
LCD	LCD	0 or 1	1
CGA	CGA	0	0
Monochrome	MONO	0	0

Notes

1. As far as I can see, the only value of type that is of relevance to Dos 7 users is EGA (which includes SVGA). Even though laptops use LCD displays, I suspect that these are not quite what the original designers of Display.sys had in mind and that EGA would be the appropriate for these machines too.
