Hi all of you, Thanks to your great advice, I finally compiled successfully BigPhysarea with kernel 2.2.19. I checked and could see the bigphysarea in /proc. Thank you again a lot. After successfully installing the kernel, I tried to compile the driver for the VideoWonder card (which comes with the SAA7110 & Zoran 36120 chip). This is the result of my "lsmod" **************** Module Size Used by soundcore 2608 0 (autoclean) (unused) zoran 23728 0 (unused) tuner 2224 0 (unused) saa7110 2592 1 videodev 2688 2 [zoran] i2c 3520 3 [zoran tuner saa7110] **************** Then I tried to check if the camera of mine works or not. I am not sure how to check it, but some website suggested me to run xawtv. I tried to install and run xawtv in X, but there are some bad errors: **************** This is xawtv-3.54, running on Linux/i686 (2.2.19) switching visual (0x25) Xlib: extension "XVideo" missing on display ":0.0". can't open /dev/video0: No buffer space available v4l-conf had some trouble, trying to continue anyway v4l2: open /dev/video0: No buffer space available v4l: open /dev/video0: No buffer space available no video grabber device available **************** Now I dont know how to go on. Is my Webcam ready to work or not, and if OK, how can I check configure for it? Thank you a lot and best wishes, VTTrang
