Uh, sorry to burst your bubble, but about the Nice SuperEISA ver.1: [you write:] : . . . . (I'm partial : to SiS for EISA, but that's just me -- and my very, very fast : machine... Sis has the fastest Gate A20 I've ever seen, too). Yup, the Nice SuperEISA ver.1 uses the SiS EISA chipset. There are other NICE EISA MB's which use a HiNT chipset, and which not only don't support bus mastering DMA above 16MB, but don't support level-triggered interrupts. Think of it as using a "Super ISA" chipset. MCCI (NICE) isn't the only company which uses this chipset, and as I've explained, it isn't the only chipset they use, either. -Ed Hall edhall@rand.org
