The et4000 is perhaps |the best chipset for non-accelerated graphics chipsets. Please give me some information. We are now planning to buy a machine with VL-local bus DX2/66 ISA machine. We are thinking 1024x768 or 1280x1024 dots colored CRT display. 1) Is the X-server for the S3 chip MUCH faster than the X-server for the chips like ET4000? How faster? If I read from the article quoted above, the XS3 is about 10 times faster than X386. Is this real now? Is there no pain for the XS3 compared from X386 for ET4000s? (No pain no gain?) 2) Does the X-server for S3 chips use the advantages of the S3 chip's instruction over the ET4000 ? I once read that S3 like accelerated cards are only effective for the MS-Windows since the card is designed to performe the primitive operations used in MS-Windows and the X386-server did not or couldn't use the functionality of the S3 chips. 3) For the VL-local bus or EISA-bus, which is 32bits wide, does the X-server really use that 32-bits width of the bus ? (Or it still uses only 16bit width transfer?) 4) I read new ET4000/W32 is quite fast or faster than S3's. Is the X-server for the ordinal ET4000 good for ET4000/W32 also? Or the X-server for the ordinal ET4000 cannot use the advantages of ET4000/W32 over original ET4000? 5) What is the fastest X-server with the combination with the G-card on the VL-bus (ISA) ? I now using ordinal ET4000(1MB) card on standard ISA bus 486DX/33MHz machine. I feel the response is a magnitude inferior than the workstations, especially when the large fonts are used. (But this may be by the CPU-Memory bottleneck and not the CPU-Gcard.)... Thank you in advance. Hiroshi Murakami mhiroshi@tansei.cc.u-tokyo.ac.jp There is no penalty for speeding by the computers.
