"hsync1/hsync2:" select the minimum and maximum Horizontal Sync Frequency of the monitor in kHz. If using a fixed frequency monitor, hsync1 must be equal to hsync2. If EDID probing is successful, these will be ignored and values will be taken from the EDID block. Recommendation: check monitor manual for correct values (default = 29/30) h. "vsync1/vsync2:" select the minimum and maximum Vertical Sync Frequency of the monitor in Hz. You can also use this option to lock your monitor's refresh rate. If EDID probing is successful, these will be ignored and values will be taken from the EDID block. Recommendation: check monitor manual for correct values (default = 60/60) IMPORTANT: If you need to clamp your timings, try to give some leeway for computational errors (over/underflows). Example: if using vsync1/vsync2 = 60/60, make sure hsync1/hsync2 has at least a 1 unit difference, and vice versa. i. "voffset:" select at what offset in MB of the logical memory to allocate the framebuffer memory. The intent is to avoid the memory blocks used by standard graphics applications (XFree86). The default offset (16 MB for a 64 MB aperture, 8 MB for a 32 MB aperture) will avoid XFree86's usage and allows up to 7 MB/15 MB of framebuffer memory. Depending on your usage, adjust the value up or down (0 for maximum usage, 31/63 MB for the least amount). Note, an arbitrary setting may conflict with XFree86. Recommendation: do not set (default = 8 or 16 MB) j. "accel" enable text acceleration. This can be enabled/reenabled anytime by using 'fbset -accel true/false'. Recommendation: enable (default = not set) k. "mtrr" enable MTRR. This allows data transfers to the framebuffer memory to occur in bursts which can significantly increase performance. Not very helpful with the i810/i815 because of 'shared memory'. Recommendation: do not set (default = not set) l. "extvga" if specified, secondary/external VGA output will always be enabled. Useful if the BIOS turns off the VGA port when no monitor is attached. The external VGA monitor can then be attached without rebooting. Recommendation: do not set (default = not set) m. "sync" Forces the hardware engine to do a "sync" or wait for the hardware to finish before starting another instruction. This will produce a more stable setup, but will be slower. Recommendation: do not set (default = not set) n. "dcolor" Use directcolor visual instead of truecolor for pixel depths greater than 8 bpp. Useful for color tuning, such as gamma control. Recommendation: do not set (default = not set) o. x[-][@] The driver will now accept specification of boot mode option. If this is specified, the options 'xres' and 'yres' will be ignored.
