- I was having my monthly drool on the Computer Shopper and I saw an ad for
- Local Bus EISA systems. No joke. Microlink, page 401 in the December
- issue has their "ELB" systems in 50 and 33 Mhz flavors for $2248 and
- $2048. I realize that this isn't VESA compliant. I'm curious, however,
- about whether it would be possible to graft VL and EISA. From what I
- understand about VL-ISA under OS/2, the usage of memory over 16MB cannot
- be handled well because of the 24 bit DMA. If there was a way to make
- the VL standard work with EISA, I think that a considerable potential
- advantage could be had in the next few years.
-
- I know that the VL standard is not the optimum standard, but I think that
- because of its future market base, it will be difficult for better systems
- based on PCI or maybe a PC variant of Quickring to get a toehold. If VL
- can have its weaknesses limited by a marriage with EISA, it might have a
- chance to avoid being cursed and villified in the future when >16MB systems
- become common.
