- EISA (given that the clock speeds on it & ISA are the same) is capable of do
- ubling the IO speed of you ISA cards (yes your ISA cards) provided the drivers
- & boards can handle the improved DMA timing. OK, your ISA boards that use DMA.
- Now, consider a factor of 2 for 32-bit EISA cards and you have a factor of 4
- possible improvement. (All EISA is 8.25 MHz).
- Of course, you can get a theoretical 200 MB/s transfer out of a 50 MHz 32 bi
- t local bus in burst mode, bu nobody does... Local bus is substantially faste
- r & when either VESA or Intel wins the latest bus war, even I might buy into it
- . So go ahead & buy one. I hope you choose wisely & if everyone picks the sam
- e, I'll join you. OTOH, I'd rather see 50 MHz EISA! IT COULD BE DONE!
