Disk Formats

When you choose the Format as... button, the disk image stored in RAM is formatted

as an empty MS-DOS disk, with a single le called Put les here...TXT. SV1115IPEXT is

able to read most MS-DOS/Windows formatted disks and presents the les via the Web

interface. However, disk emulation occurs at the lowest level so that 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 oppy. Images of

other sizes are supported up to 8MB.

CD-ROM Mode

The SV1115IPEXT 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 le. This is a byte-for-byte copy of track one (the data track) of a data

CD-ROM. The ISO le must be made available on a web server that can be accessed

by SV1115IPEXT. 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 le for access.

If successful, you will be shown a short report on the le 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 SV1115IPEXT can access directly.

• An image of a bootable CD-ROM disk can be used by the BIOS to boot an operating system.

• The image le itself may be any size, but it will typically be less than 700 megabytes.

Normally this le will be an ISO image (an ISO-9660 le system) but any disk image

may be used.

• 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.
