Options to bypass Keyboard/Video/floppy errors for Dedicated file servers
|
|||
|
|
or similar applications...
|
|||
|
|
|
|||
|
|
This release of AMI BIOS can be configured to do one of the following:-
|
|||
|
|
|
|||
|
|
- Bypass testing Keyboard and/or Video and/or Floppy controller
|
|||
|
|
during Power on self test.
|
|||
|
|
|
|||
|
|
- Test all during Power on self test but in case of Keyboard and/or
|
|||
|
|
Video and/or Floppy controller errors do not wait for user to press
|
|||
|
|
the "F1" key.
|
|||
|
|
|
|||
|
|
To configure the BIOS as above at your facility, you need the new AMIGEN
|
|||
|
|
program. You can buy the AMIGEN program from AMI if you do not have
|
|||
|
|
one. If you already have an AMIGEN program you can get the updated
|
|||
|
|
AMIGEN program and new release of the BIOS by paying nominal charges.
|
|||
|
|
Please refer to the price list for BIOS update for details.

|
|
Support for additional serial ports...
|
|||
|
|
|
|||
|
|
AMI BIOS will now look for additional on board or off board serial ports
|
|||
|
|
upto a maximum 4 ports. These serial ports will be assigned port numbers
|
|||
|
|
3F8,2F8,3E8,2E8 as COM1, COM2, CMO3, COM4 respectively. However, the
|
|||
|
|
BIOS support for COM3, COM4 is limited to integrating them into the
|
|||
|
|
system. The BIOS will support data transfer and programmability for COM1
|
|||
|
|
and COM2 only.

We have added a boot up screen for all types of BIOS with diagnostics
|
|||
|
|

|
|||

User defined drive type...
|

The AMI BIOS supports 46 predefined drive parameters. There will be
|
|||
|
|
occasions when you have a drive which does not match with any one of
|
|||
|
|
these 46 drive types. In these cases, you can use this new feature in AMI
|
|||
|
|
BIOS by which you can specify drive parameters through the CMOS SETUP
|
|||
|
|
program. These parameters will be stored in the CMOS. The type of drive
|
|||
|
|
will be type 47 which will be referred to as "USER DEFINED DRIVE

|||
|
|
