I don't know too much about the specifics, but I can see on boot up that 
FreeBSD supports multi-block 16 and 64 on my two drives along with 32 
bits.  Although it does seem to misprobe and assume multi-block 16 on 
ide drives that don't handle it.

I believe these options need to be activated when you compile the kernel. 
It does recognize my 3 hard drives on an EIDE controller (DTC 2728 Dual
Port 4hd/2fd version), but the controller seems to be slower than the
non-EIDE VLB 2hd/2fd controller which I have gone back to using.  I doubt
if this is FreeBSD's fault because even in DOS, the controller is slower
than the generic VLB controller I use.  (With no drivers in DOS, I get about 
3.5 MB/s on the generic, and 1.8 MB/s on the DTC.  With DOS drivers, I get 
4.6 MB/s on the generic, and about 3.6 MB/s on the DTC.)

Anyone have any good recommendations on inexpensive VLB 4HD/2FD EIDE 
controllers?
