My position in Phoenix is a kernel engineer to develop the BIOS features. In the beginning, I took the display part (precisely speaking, console) of the UEFI structure. Then I touched and improved the functions of the BIOS-flashing and HDD password. My achievement for BIOS-flashing is a DoS tool. Also, for HDD password I implemented some items on the BIOS setup menu.

In Motorola, I worked for the setup-box team to develop the platform code based on Linux. Motorola the functions I was responsible for are the following:1. Tuning: adjusting the parameters such as frequency and modulation when channel 2. data path: parsing and passing the MPEG PESes to the proper engine, such as A/V decoder or a file to record.3. PVR: implementing the functions to record, to playback and Time-Shift.

At SiS, I was the ONLY developer of Linux VGA drivers for the latest 2 generation chip, which are SiS671 and SiS662. The domains I covered were the following:X-window VGA driver: 1. Display functionalities of CRT & LCD panel. 2. Video play back functions (overlay, for YUV format) 3. Motion Compensation of MPEG (XvMC)Kernel mode driver 1. Frame buffer driver (SISFB, for text mode) 2. AGP & DRM kernel module.Some links to record my activities with Linux Community are attached.
