Smsc Scsi & Raid Devices Driver Downloads
If you can't find your beep code in our list, you can use the following method to identify the defective hardware:
- Remove RAM memory, Graphics card, other Plug-in cards, and Drive cables from your mainboard.
Only CPU + Fan + Power cable are installed on the mainboard. - Power on the PC, and listen to the beeps:
- no beeps => Power supply, CPU, mainboard or BIOS is most likely defective.
- some beeps => remember the beeps and next step.
- Power off the PC, and insert the RAM memory.
- Power on the PC, and listen to the beeps:
- no beeps => RAM incorrectly installed.
- same beeps as before => RAM is most likely defective.
- beeps have changed => next step.
- Power off the PC, and insert the Graphics card.
- Power on the PC:
- some beeps => Graphics card is most likely defective.
- blank screen =>Graphics card is most likely defective.

What is smsc-ece1099?¶
The ECE1099 is a 40-Pin 3.3V Keyboard Scan Expansionor GPIO Expansion device. The device supports a keyboardscan matrix of 23x8. The device is connected to a Mastervia the SMSC BC-Link interface or via the SMBus.Keypad scan Input(KSI) and Keypad Scan Output(KSO) signalsare multiplexed with GPIOs.
Interrupt generation¶
Interrupts can be generated by an edge detection on a GPIOpin or an edge detection on one of the bus interface pins.Interrupts can also be detected on the keyboard scan interface.The bus interrupt pin (BC_INT# or SMBUS_INT#) is asserted ifany bit in one of the Interrupt Status registers is 1 andthe corresponding Interrupt Mask bit is also 1.
In order for software to determine which device is the sourceof an interrupt, it should first read the Group Interrupt Status Registerto determine which Status register group is a source for the interrupt.Software should read both the Status register and the associated Mask register,then AND the two values together. Bits that are 1 in the result of the ANDare active interrupts. Software clears an interrupt by writing a 1 to thecorresponding bit in the Status register.
Communication Protocol¶
- SMbus slave Interface
The host processor communicates with the ECE1099 devicethrough a series of read/write registers via the SMBusinterface. SMBus is a serial communication protocol betweena computer host and its peripheral devices. The SMBus datarate is 10KHz minimum to 400 KHz maximum
- Slave Bus Interface
The ECE1099 device SMBus implementation is a subset of theSMBus interface to the host. The device is a slave-only SMBus device.The implementation in the device is a subset of SMBus since itonly supports four protocols.
The Write Byte, Read Byte, Send Byte, and Receive Byte protocols are theonly valid SMBus protocols for the device.
- BC-LinkTM Interface
The BC-Link is a proprietary bus that allows communicationbetween a Master device and a Companion device. The Masterdevice uses this serial bus to read and write registerslocated on the Companion device. The bus comprises three signals,BC_CLK, BC_DAT and BC_INT#. The Master device always provides theclock, BC_CLK, and the Companion device is the source for anindependent asynchronous interrupt signal, BC_INT#. The ECE1099supports BC-Link speeds up to 24MHz.
