The '''VIDE-CDD.SYS''' driver is an IDE CD-ROM device driver from Acer. It is one of the smallest DOS CD-ROM drivers available.

== Parameters ==

; <tt>'''/D:''device'''''</tt>
: Sets the driver name to use. Typical use is <tt>/D:MSCD001</tt>. Must match the <tt>/D</tt> option passed to <tt>[[MSCDEX.EXE]]</tt>.
; <tt>'''/P:''xxx'',''yy'''''</tt>
: Indicates the port and IRQ of the IDE interface. <tt>xxx</tt> is the I/O address in hex, and <tt>yy</tt> is the IRQ in decimal. The default values if none are specified are:
* <tt>/P:1F0,14</tt> (primary)
* <tt>/P:170,15</tt> (secondary)
* <tt>/P:1E8,12</tt> (tertiary)
* <tt>/P:168,10</tt> (quaternary)

: Note that the IRQs for the tertiary and quaternary interfaces are not standardised, so they will need to be specified manually if they don't match the defaults listed here.

== Examples ==

Handle up to eight drives across all four IDE interfaces:

<pre>
DEVICE=VIDE-CDD.SYS /D:MSCD001 /P:1F0,14 /P:170,15 /P:1E8,12 /P:168,10
</pre>

== Output ==

A successful install produces a message similar to the following:

<pre>
IDE/ATAPI CD-ROM Device Driver Version 2.11 17:30:39 06/07/96
CD-ROM drive #0 found on 1E8h port master device, v3476
</pre>

== Compatibility ==

This driver also does not appear to detect drives if the second set of I/O addresses are incomplete. A notable example is the [[Creative Sound Blaster 32 PnP]] series of cards, which only makes port 376 available when set to the secondary IDE interface, whereas ports 376-377 should be accessible. In this case, the card needs to be set to tertiary or quaternary in order to work, and as this option uses a different IRQ to the defaults above, the <tt>/P</tt> option must be used.
