From 1237c98db2aa94b42dbb9fb1df062b7d3733dc83 Mon Sep 17 00:00:00 2001 From: Gilbert Wu Date: Mon, 22 Oct 2007 15:19:11 -0700 Subject: [SCSI] aic94xx: update BIOS image from user space. 1. Create a file "update_bios" in sysfs to allow user to update bios from user space. 2. The BIOS image file can be downloaded from web site "http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300" and copy the BIOS image into /lib/firmware folder. 3. The aic994xx will accept "update bios_file" and "verify bios_file" commands to perform update and verify BIOS image . For example: Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios" to update BIOS image from /lib/firmware/as483c01.ufi file into HBA's flash memory. Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios" to verify BIOS image between /lib/firmware/asc48c01.ufi file and HBA's flash memory. 4. Type "cat /sys/devices/.../update_bios" to view the status or result of updating BIOS.
