-/* Note to users trying to share a disk between DOS and unix:
- * The ST01/02 is a translating host-adapter. It is not giving DOS
- * the same number of heads/tracks/sectors as specified by the disk.
- * It is therefore important to look at what numbers DOS thinks the
- * disk has. Use these to disklabel your disk in an appropriate manner
- *
- * About ST02+IDE coexistence: the original Seagate ST02
- * BIOS cannot coexist with IDE or any other disk controller
- * because it does not share BIOS disk drive numbers (80h, 81h)
- * with others.  New probing code allows using ST02 controller
- * without BIOS: just unplug the ST02 BIOS chip from the board.
- *
- * Another problem is the floppy adapter on ST02 which could not be
- * disabled by jumpers.  I commonly use ST02 adapter as a cheap solution
- * for atttaching the tape and CD-ROM drives, and an extra floppy controller
- * is just a headache.  I found a simple workaround: cutting off
- * the AEN signal (A11 contact on ISA connector).  AEN then goes high and
- * disables the floppy adapter port address decoder.
- *
- * I also had a problem with ST02 conflicting with IDE during
- * IDE data write phase.  It seems than ST02 makes some noise
- * on /IOW line.  The /IOW line is used only for floppy controller
- * part of ST02, and because I don't need it, I cut off the /IOW (contact B13)
- * and it helped. (vak)
- *
- * Tested on the following hardware:
- *   Adapter: Seagate ST02
- *      Disk: HP D1686
- * Streamers: Archive Viper 150, Wangtek 5525
- *   CD-ROMs: Toshiba XM-3401, NEC CDR-25
- *
- * Maximum data rate is about 270-280 kbytes/sec (on 386DX/40).
