SEPTEMBER 2005 MAGNUM 1X7 LTO AUTOLOADER

25-1

WRITE BUFFER (3Bh)

25.1 ABOUT THIS COMMAND

The BUFFER WRITE allows you to load new microcode (also known as

firmware) across the SCSI bus into the autoloader’s flash EEPROM. The

autoloader processes this command when it is executing the flash EEPROM

code or when it is executing the ROM boot code.

Note: If new microcode becomes available, you can obtain a copy (in

machine-readable form) from your vendor or download it from Exabyte’s

web site (www.exabyte.com).

If the initiator has less than 131,072 (020000h) bytes of buffer space available,

you may want to issue more than one WRITE BUFFER command to transfer

each section of the microcode.
