The new version of DC-620(B) ( with BIOS/FIRM version greater than 2.01 ) supports EISA ID. This enables the EISA configuration utility to recognize DC-620(B) as an EISA controller. The configuration file ( !TRM0620.CFG ) is used for EISA card identification only. To run the ECU (EISA Configuration Utility), you have to copy this configuration file to your ECU diskette first. All other options of the controller must be set within the ACM by pressing F2 or F6. There is no functional discrepancy between running the ECU for DC-620(B) or not. The major difference would be the warning message, "Invalid configuration information for SLOT ?", if not running the ECU. Once again, you can ignore this warning message without any side effect.
