Addonics PCMCIA interface support in Linux (Redhat 5.2)


Due to the increasing inquiries in to support for Linux, and the announcement by major manufacturers to support Linux in their machines, we began to research the use of the Addonics products mentioned above in the Linux format.

Currently, we have been able to successfully use the above PCMCIA CD-ROMs in Linux using Redhat 5.2. There were no additional software or drivers required. Redhat 5.2 has built in PCMCIA support, and emulates plug and play. When the PCcard is inserted the computer detects as a HDC. Linux recognizes devices in the following manner.

  1. Hda1 This is the first partition of the first drive on the IDE controller
  2. Hda2 This is the second partition of the first drive on the IDE controller
  3. Hdb1 This is the first partition of the second drive on the IDE controller
  4. Fd0 This is the floppy drive
  5. Hdc This is the hard disk controller

 To load the drives in Linux use the MOUNT command. To mount devices you must tell the computer where to get the driver from and where to mount the drive to (the directory to see the files). Therefore to mount the CD-ROM when it is recognized as HDC, use the following command:

Mount /dev/hdc /mnt/cdrom

This tells the computer to go the /DEV directory and use the HDC controller. Then to put device to the /MNT/CDROM directory so the files can be read. If the /MNT/CDROM directory does not exist, they can mount the CD-ROM to any other directory or create the directories (mkdir):

Mkdir cdrom

 You move through directories by typing CD:

&Cd cdrom

 Once in the directory type in DIR to see the files in the directory.

 The other method to mount drives is to use Xwindows and under AdministrationDisk Management. In here each device is listed. Simply click the mount/unmount button to mount the drive.
