Major Changes since last release:
=================================

1.  A larger drive in an array of two identical size drives can be replaced with a drive of slightly smaller size and rebuild will start.  Fixed.

2.  Added support for new flash part

3.  Fixed problem when there are two media errors on different drives for the same row.

4.  Fixed boot loop hang on some systems.

5.  Fixed problem getting into CTRL-M on some systems.

6.  Cannot rebuild drives if created on 320-2 and controller is swapped to 2x.  Fixed.

7.  Time stamping in the NVRAM log is one day behind. For example the time
stamp should be 2/8/2004, instead it logs 2/7/2004.  Fixed.

8.  When cascading two backplanes and attached 3 HDD as a RAID 5 drive, the RAID can auto rebuild at 1st time after they unplug a HDD and re-insert the HDD, but 2nd time and after can't auto rebuild.  Fixed.

9.  Fixed problem with a rush of SCSI BUS Resets.

10.  While using JMR enclosure and running IO, the HDD (ONLINE disk) didnt perform auto-rebuild when it was unplugged and then re-inserted.  Fixed.

11.  Setup WB while card has no battery. Created a DOS partition and quickly warm booted the system. The DOS partition did not exist when checked after reboot.  Fixed.

12.  In some enclosures, the SAF-TE led does not stop blinking even after check consistency or rebuild gets over.  Fixed.

13.  During validation of Dirty cache at bootup, fixed problem if ECC errors encountered.

14.  Background Inititialization performed only on redundant arrays with five or more physical drives.

15.  Numerous fixes and enhancements to CTRL-M and WebBIOS.


Important Notes:
================
1.  This firmware image does NOT contain the 64-bit EFI Driver, though it will work in legacy mode on IA64 systems.

2.  The default for LDs is 2k currently in webBIOS. It should be 64k to match other utilities.  Please make the change if using WebBIOS.

3.  There have been some reports that CTRL-M or WebBIOS cannot be entered on some newer platforms.  This is being investigated.

4.  The Alarm on the MegaRAID controller is disabled by default.  Enable it in CTRL-M if the alarm feature is desired.

5.  The previous release (1L26), performed Background Initialization (BGI) on all redundant arrays.  With the release, BGI is only performed with RAID 5 arrays with five or more physical drives.


Installation:
=============
MAKE SURE TO FLASH THIS FIRMWARE ONLY WHEN USING A MEGARAID SCSI 320-1 OR 320-2 CONTROLLER FROM LSI LOGIC CORPORATION.

1. Create a bootable floppy.  This floppy should be a basic boot disk without a config.sys or autoexec.bat; if using a Windows 98 Boot disk, bypass these files by holding down the left shift key. 

2. Take a second blank floppy, and extract all the files from the .ZIP with the firmware in it.

3. Reboot the system, and boot from the DOS bootable floppy.  At the A:> prompt, remove the first disk and insert the second disk.

4. At the A:> prompt, type MFLASH and hit enter.  The MegaRAID flash utility will start.

5. There will be prompts asking if this is the correct adapter, and the correct image.  Say yes to both.

6. The firmware will flash.  There will be a prompt to reboot the system When the controller has been completely flashed.
