- BIOS TYPES AND ISSUES
-
- AMI (Quatel) BIOS
- AMI Bios dated 4/91 or later will not have any of the
- handshaking problems with IDE controllers and hard drives.
- The problem seen with earlier versions of Bios and IDE hard
- drives was that our tape software had to run in non-concurrent
- mode to solve timing issues.
-
- AT&T BIOS
- To run the Jumbo tape drives you need to have AT&T Bios 1.21
- or greater.
-
- AWARD BIOS
- Our tape software must run non-concurrent mode when using
- Award Bios previous to version 3.05 with our tape software.
- 1. Award Bios 3.05 solved the Conner hard drive/IDE
- handshaking problem.
- 2. Can run our tape software in concurrent mode.
- 3. These problems are only relevant to DOS (No effect on
- Unix/Xenix).

- DTK BIOS
- There is a timing issue when DTK Bios version 4.26 rev. 4 or
- earlier was used in conjunction with IDE hard drives. This
- showed up with our tape software and drives as "Error reading
- drive C" during total backups.
- DTK Bios can be identified by serial number. Example: After
- the # sign, the first number designates the CPU type (2 is for
- 286, 3 is for 386, etc.). The second number designates
- revision number. Revision 3 or higher is recommended for use
- with IDE. Revision 5 has corrections for the timing problems
- seen with IDE hard drives.
- Upgrades of this bios are available through Barlett Computers
- of Chicago at 708-830-4222.
-
- IBM PC BIOS
- To run the Jumbo tape drives you will need IBM PC Bios dated
- later than October 1984. If earlier bios is used you will see
- lockups during installation of software.
-
- PHOENIX BIOS
- Phoenix Bios dated previous to 1989 will have problems with
- IDE controllers and tape drives. 386 version 1.10 runs from
- January 1988 through December 1989 and was updated in May of
- 1989 to handle IDE's. The 286 Bios versions are up to 3.10
- but still falls into the same time constraints as the 236 Bios
- versions.
