Instruction Manual

SVxx53DXI is able to read most MS-DOS/Windows formatted disks and presents the files
via the Web interface. However, disk emulation occurs at the lowest level, so other disk
formats can be used if you have the tools needed to create and read the disk images.
At the bottom of the page are the upload and download options for the entire disk
image. Any image that is exactly 1,474,560 bytes long will be treated as a floppy.
Images of other sizes are supported up to 8MB.
CD-ROM Mode: The SVxx53DXI does not store any data in this mode. Instead, it
emulates a USB CD-ROM drive with a disk inserted. The data from that disk must be
provided by an external web server. You will need a copy of the CD-ROM contents that
you want to emulate as an ISO file. This is a byte-for-byte copy of track one (the data
track) of a data CD-ROM. The ISO file must be made available on a web server that can
be accessed by SVxx53DXI. To switch to this mode, type in a URL pointing to the ISO
image, and click on Commit. The system will connect to the web server and test the file
for access. If successful, you will be shown a short report on the file contents, and the
disk will be ready to use.
Currently there is no other way to preview or browse the contents of the CD-ROM
image, except from the host.
CD-ROM Web Server Requirements:
• Data must be hosted on a web server that the SVxx53DXI can access directly.
• An image of a bootable CD-ROM disk can be used by the BIOS to boot
an operating system.
• The image file itself may be any size, but it will typically be less than
700Mb. Normally this file will be an ISO image (an ISO-9660 file
system) but any disk image may be used.
• The web server must support “byte ranges”. Persistent connections are
used, if available, as this greatly improves performance. “Read-only”
access is provided; writing is not supported.
• CD-Rom block size must be 2048 bytes. Unfortunately, XA-Data type
tracks are not supported.
