Disk Support

To configure disk support on the COMX select fdc.bin in any available slot (CARD 1 if no expansion box is used), see example below (yellow ellipse):

At least one COMX disk image is needed (as Disk 1, orange ellipse) to boot COMX DOS. The Emulator has installed the master disk image 'dos.1.4+f&m.disk.tools.img'. When DOS NEW is used the COMX DOS should be initiated as below:

After this any DOS command or utility from the master disk can be used, for explanation of COMX DOS commands please see the COMX DOS manual available on the Dutch COMX Club.

To change the disks at run time just select a different filename via one of the Disk x buttons (orange or blue ellipse) or type a name in the text field. To eject the disk use the eject button or remove the filename in the text field.

Disk Format and boot initialisation

To create a new disk image including COMX DOS boot data, keep 'dos.1.4+f&m.disk.tools.img' specified as Disk 1 (orange ellipse) and any filename of your choice as Disk 2 (blue ellipse):

To format a disk use DOS URUN,"INIT" and make sure to select drive No. 2 when asked on what drive to format! See examples for 3 different disk options below.

1. Double sided disk, 35 tracks per side with a total size of 140K:

2. Single sided disk, 70 tracks with a total size of 140K:

3. Single sided disk, 35 tracks with a total size of 70K:
