**Spelling errors/mistyped words
Yes, I  know there are  spelling errors,  and things are  mistyped. It
seems no matter  how hard I try  my fingers hit 't'  twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times.  I  don't have the  time or the will  to check the  spelling of
everything. Basic spell checking has been peformed. Please let me know
if  there is  anything that  would lead  to incorrect  information, or
something  is so  mangled  that  it needs  revising.  But  if you  can
basically  understand  what was  intended,  just  cope with  it.  Just
cope:-)

BTW, "110" port is  an "I/O" port that has been OCRed  badly, as is an
"1/0" port.

**W83759/A/F/AF   Advanced VL-IDE Disk Controller                  <96
***Notes:...
***Info:...
***Versions:...
***Features:
o  Pin-to-pin backward compatible with W83759 VL-IDE Interface chip
o  VESA VL-Bus Rev 2.0 compatible, connects directly to local bus and 
   four IDE drives
o  Direct interface to various ANSI ATA/ATA-2/FAST ATA/IDE-2/Enhanced 
   IDE drives
o  Supports 32 and 16-bit data transfer
o  Fully software programmable for command active/recovery time and 
   address setup, data hold time
o  Built-in VL-Bus to 16-bit IO data buffer for special applications
o  Fully supports Enhanced IDE features, including Fast PIO, Mode 3/4, 
   IORDY flow control, prefetch control
o  Supports dual channels to allow up to four drives or non-disk 
   devices (ATAPI CD-ROM and tape drives)
o  Pipeline pre-fetched reads and posted writes for concurrent disk 
   and host operations
o  Independent access timing for all drives (primary/secondary and 
   master/slave)
o  All Enhanced IDE new features may be disabled/enabled via driver 
   or power-on setting by per drive selectability
o  ATA/Mode 0-4 PIO speed may be set as default timing of each drive 
   via power-on jumper setting
o  Supports slave DMA mode protocol (reserved)
o  Supports auto power-down, standby, suspend APM power management 
   state for green PCs
o  Primary and secondary channel can be independently enabled/disabled 
   by software or jumper setting
o  Supports drivers for DOS, Windows, OS/2, UNIX, and Netware
o  Packaged in 100-pin QFP
