I have a dual Xeon cpu board with onboard ASMB8 iKVM. The iKVM is not that great but you can use it for what you need to do. It uses Java console for kvm and loading ISO for remote OS install.

I was using the kvm for remote connection / reboot but what I found was that after using it for a short while it became unresponsive until the physical host power was removed and re-plugged (ie reboot the module). So when I saw that there was a newer firmware available I jumped at the chance to load it.

I loaded the 1.16.1 ASMB8 firmware via the ikvm web gui. I noticed that it had cleared the configuration but this was no bother to me because I had only configured a new user and password. So I retrieved the default username and password from the manual for logging in after the update - which didnt work!

Many hours searching the web - without any success for logging in to this ikvm any longer. I think the default credentials are different in this firmware compared to the original document that is from 2014.

"Screwed." I thought. Then I happen to notice the document says I can run a command to set a new password. In what context I didnt know. One google result showed me that I could run this command using ipmitool from the ubuntu OS but it was not finding any /dev/ipmi device.

So here are the steps I took to resolve the issue:

1. download the current / latest firmware zip (make sure its the correct firmware for the actual device because will brick otherwise)
2. create a bootable floppy usb from RUFUS
3. drag over the contents of the firmware zip file into the root of the floppy usb
4. flash the firmware
5. once flashed, execute ASMC8.EXE -adm_password newpassword
6. now can log in with user "admin" and password "newpassword"

BTW floppy drives no longer supported in latest linux kernel. Bye bye floppies!
