[ ton of neat stuff deleted ] If you still have all that stuff handy, could I ask for a repost telling which controllers have hardware buffering and which use the BIOS? I found that the Adaptek 2372 was a factor of three slower than the WD1006CSR2 because Xenix doesn't use the BIOS. My understanding is that some flavors of UNIX do software track buffering on any controller (which takes CPU) and some just use the controller, in which case the hardware is faster.
