There are several improvements that should be noted: > - Real support for the S3 86C928 (no Hack needed); the server defaults > to use the Memory-Mapped-IO (mmio) routines for 928 boards which give > a significant performance boost on some operations. This can be > overruled with the 'chipset "s3_generic"' keyword. For quite sometime, XS3 has worked with the 928 cards;however, the linux support has lacked behind. XS3.mmio does use memory mapped i/o. > - Support for programmable clocks (for the icd2061a programmable clock > "icd2061a" and "icd2061a_slow".

Again, for quite sometime we have had the capability to program the ICD2061 programmable clock. The code was tested against the ELSA Winner 1000 and the #9 928 cards. > - Better support for external clock programs than with XS3. See the > Xconfig(4/5) manpage and README.clockprog for details. > - More than 1MB Videoram supported. The videoram setting is usually not > needed in Xconfig. Some 512k boards seem to be exceptions. Again, we do support more than 1MB Videoram. Currently, typing all this at 1280x1024 clock rate 110Mhz. > - Rudimentary support for Brooktree Bt485 RAMDACs (full support will be > available shortly). This basically means that on boards with the Bt485 > the maximum dot clock frequency is restricted to 85MHz. These boards > are for example the #9GXe, the Metheus Premier and the ELSA Winner 2000. XS3 does not restrict the user to 110Mhz there is a bug which does not restore the screen properly;however, with the XFree86 I am stuck by not been able to run at clock rates greater than 110Mhz. > - VT switching supported. Phew, this is true. > - The x-resolution is not restricted to 1024, and can be up to 1280. We do support 1280x resolutions. -------------------------------------- BUG: XF86_S3 refuses to accept my 110.200Mhz clock for 1280x1024;hence, I am force to use 1280x1024 in interlace mode. The 110.200 clock was reported by XF86_S3.
