Figure 5-2. Multi-portable Drivers
Note:
• These devices must be self-powered since the Hub cannot provide enough current to each ATAPI/IDE device.
• We recommend that a PC for this configuration be at least a 300-MHz Pentium® II with 64 Mbyte RAM

How to Update the SL11RIDE Firmware
The firmware on the EEPROM doesn’t have to be changed after it is downloaded for the first time. If it needs to be changed during
testing or for future firmware updates, this can be done from a PC using the USB port. The need to change firmware to switch
between an ATAPI device and an IDE device will be removed in a future release.

The QTUI2C Program
6.2.1
Overview
The QTUI2C program is used to program the I2C EEPROM that is externally connected to the SL11RIDE chip. This allows
programming the I2C with data alone, such as the USB data descriptors. The SL11RIDE will scan the I2C for a valid signature
before attempting to load the code and/or data to the internal/external RAM.
To program the file, the input filename without the extension is required. The QTUI2C will create a file “MAKEENH.BIN” based
on the Object input file. This “MAKEENH.BIN” file will contain the fix-up (.bin) information and it will have a proper format that is
defined on the SL11RIDE BIOS specification.
