Critical errors are due to:

• Physical hardware failure: the disk does not exist or it has a wrong configuration (e.g: IDE bus, check for MASTER and/or SLAVE).
• Wrong BIOS configuration: Please check that the hardware is correctly configured (HDD, RAID controllers).
• If all of the above is correct, then the IPBrick CD that you have shouldn't support your specific hardware configuration. Please send your hardware description and configuration by mail to support@ipbrick.com. You will be contacted by the IPBrick Technical Department.
