IPC@CHIP Documentation Index BIOS Interrupts Here are the interface definition for the BIOS Interrupts BIOS Interface Documentation - SC12 @CHIP-RTOS V1.10 The system BIOS in a regular PC offers many services, only a subset of which is required in embedded systems. This subset is described here. Unsupported BIOS functions are handled by a default handler which issues a message to the console. Some additional functions not found in a normal PC BIOS are provided for your convenience. For some useful comments see Programming notes New in version 1.10B: Extended: Get serial number New in version 1.10B: Extended: Get @CHIP-RTOS features New in version 1.10B: Extended: Install User Fatal Error Handler with Low Mem Error New in version 1.10B: Extended: Get the IPC@CHIP device names New in version 1.10B: Read/Write persistent user data New in version 1.10B: Get IP address of the PPP Server New in version 1.10B: Get IP address of the PPP Client New in version 1.11B: Get sprintf address ● Interrupt_0x1A_function_0x00:_Get clock count since midnight ● Interrupt_0x11_function_0xXX:_Get equipment list ● Interrupt_0x10_function_0x00:_Get char from standard input ● Interrupt_0x10_function_0x01:_Check if a character is available from std in ● Interrupt_0x10_function_0x08:_Read character at cursor ● Interrupt_0x10_function_0x0E:_Teletype output ● Interrupt_0x10_function_0x0F:_Get video state ● Interrupt_0x10_function_0x12:_Video subsystem configuration ● Interrupt_0x16_function_0x00:_Get char from standard input ● Interrupt_0x16_function_0x01:_Check if a character is available from std in ● Interrupt_0xA0_function_0x00:_Get serial number ● Interrupt_0xA0_function_0x01:_Get IP address of the Ethernet interface ● Interrupt_0xA0_function_0x02:_Set IP address of the Ethernet interface ● Interrupt_0xA0_function_0x03:_Get IP subnet mask of the Ethernet interface ● Interrupt_0xA0_function_0x04:_Set IP subnet mask ● Interrupt_0xA0_function_0x05:_Get IP gateway ● Interrupt_0xA0_function_0x06:_Set IP default gateway ● Interrupt_0xA0_function_0x07:_Execute a command shell command ● Interrupt_0xA0_function_0x08:_Set timer 0x1C's interval ● Interrupt_0xA0_function_0x09:_Set timer interrupt 0xAF's interval ● Interrupt_0xA0_function_0x11:_Set STDIO focus ● Interrupt_0xA0_function_0x12:_Get bootstrap version number ● Interrupt_0xA0_function_0x13:_Get @CHIP-RTOS version number ● Interrupt_0xA0_function_0x14:_Set batch file execution mode. ● Interrupt_0xA0_function_0x15:_Allow immediate further batch file execution in BATCHMODE 1. ● Interrupt_0xA0_function_0x16:_Get information about the @CHIP-RTOS features ● Interrupt_0xA0_function_0x17:_Get MAC address of the Ethernet interface ● Interrupt_0xA0_function_0x18:_Power save Page 76 / 400

The frequency of the clock is 18.2 Hz (e.g. 54.945 ms per tick). Parameters AH Must be 0. Return Value Comments Top of list Index page Returns the 32 bit tick count in CX (high word) and DX (low word) If an overflow occurred since the last call, AX is set to 1. Please note that the overflow indication returned in register AX can not be relied upon if several tasks are using this service. Interrupt 0x11 service 0xXX: Get equipment list Get the BIOS equipment list Return Value Returns the equipment list in AX, currently 0x013C.
