prior to this it was stuck permanently stating " checking printer" would never advance further than this, cannot print anything but engine tests, can get into pre-boot menu no problem, tried another formatter but was unable to use it do to the encrypted disk drive was locked to that formatter and did not want to monkey around with the data on it as it was a good working unit that belonged to another department, i installed another disk in it and loaded the firmware to it, however the problem appears on either disk, so i have a big giant paper weight now with flashing lights, the error does not appear in the service manual.
