µFlashTCP-EP

User’s Manual

microsystems

Applications

The µFlashTCP-EP is compatible with a variety of interface drivers, TCP/IP stacks and network
software. Discussion of the installation and operation of these packages is beyond the scope of
this manual. Please refer to the software documentation or contact JK microsystems.

Some care is required when setting up the µFlashTCP-EP on a network. Contact the Network
Administrator if there are any questions about the required information. When working with a
TCP/IP network, obtain the following information before starting your configuration: IP Address,
Subnet mask, Name Server address (DNS), and Gateway address. This information will be
required during the configuration process. Other types of LANs require node names, workgroup
names, etc. Proceed cautiously, networks can be easily disrupted when nodes are added without
careful configuration.

Supported PC BIOS Functions

The Flashlite BIOS supports the following functions (software interrupts) common to PC
compatible computers. Please refer to a DOS/PC reference for more information on DOS and
BIOS software interrupts.

Int 10h, Video Driver, functions 9 and Eh
Int 11h, Get Equipment Configuration
Int 12h, Get Memory Size
Int 13h, Disk Driver, Functions 0-4
Int 14h, Serial Port Driver, Functions 0-3
Int 16h, Keyboard Driver, Functions 0 and 1
Int 19h, Boot System
Int 1Ch, Hook Timer Tick Interrupt
IRQ0, Timer Tick Interrupt
