I too have encountered a hung flash. There are several options to recover.
If the last 64KB BIOS block is still intact, the IBM Flash BIOS Boot Block recovery image (for the Intellistation A-pro type 6224) may work, that is after modifying the image with the SUN BIOS. The BIOS recovery jumper on the motherboard would need to be set (see IBM's documentation about this) when booting the recovery CD. Attach a speaker to the workstation to hear the beeps.
If the recovery procedure does not respond at all, then the w1100z BIOS chip will need to be removed (it's in a socket), and reprogrammed externally or replaced. The BIOS chip is SST49LF080A flash and can be programmed directly with the *.flh image in the Sun BIOS update CDs. If you have access to a computer lab with a programmer, your all set (if not, please drop me a note).
To date, I haven't yet found a small quantity source for the flash chip, even for blank ones.
Flash utility phlash16 v1.3 build 41 has given me the most trouble with hangs in the past. The older Sun supplement CDs and the latest supplement CD 2.5 include later and more reliable versions of phlash16.
Did you use the internal CD drive or a USB attachedUse the internal CD drive. The BIOS recovery boot block has no video capability and probably does not have usb capability either.
There is a jumper that can be set to reset the BIOSThere's another jumper to erase/reset CMOS settings. That's different than booting the recovery boot block. The recovery boot block jumper is JP2 (description "unknown") in the sun handbook.
back to the default. You set the jumper, power on the
system, wait about a minute or so, then restart the
system with the BIOS CD in the CD drive. This has
helped me get out of jams.
I seem to be facing the same problem after upgrading a w2100z from R01B4S0 to LATEST ( R01B5S1 ). ( w2 / w1 stand for number of processors in the box )
The bios flashing went perfectly but the machine never came back after the system reboot.
After power on the system initializes it`s video card and stands there ( probably never completing POST ) and the strange thing is that i can type anything on the keyboard and only F8 and F12 seem to generate a response from the system.
Pressing F8 results in the monitor printing "4pt" and F12 some oOo sign ( rotate at 90degrees ).
I've cleared the CMOS Settings ( JP1 pins 2 - 3 ) and put the motherboard into recovery mode ( JP2 set to pins 2 - 3 ) but once in recovery mode it starts beeping a VGA Card Error ( 1 long 2 short )
In this state i've tried booting with the ibm intellistation 6224 recovery cd modified to include the SUN R01B4S0 Bios with no success whatsoever..
i've tried combinations like putting the bios file on a cd by itself / using the supplement 2.0 cd / modifying the ibm flash recovery disk ( modified and unmodified ) and powering on the machine..
I've even tried all of these while holding ALT + HOME and powering up the workstation.
No success till now.
If you have some suggestions on how to fix this they will be welcome.
Thank you for taking the time to read my post.
Do a clear CMOS operation first, and be sure to power down, restore the jumper to original position, and power back up. If you still can't recover the workstation, try reducing the hardware configuration to bare minimum. If still no go, then you can try the BIOS recovery jumper. Do not set both jumpers.
For the BIOS recovery CD, be sure to verify that it's a bootable CD.
In recovery mode, the only feedback is audio (hook up speakers to line out to get audio). As long as there's audio, the BIOS recovery code is alive. If you think it's beeping a VGA card error, then try removing the card. There's no video anyway in recovery mode.
