The Promise Technologies model 4030VL VESA local-bus-cached IDE controller card and the model DC200 ISA-cached IDE controller card both need a firmware update to run properly with the MS-DOS 6.0 DoubleSpace disk- compression program.


There are three EPROMs for the model 4030VL controller card. Check the last four digits of the EPROM number. If the last four digits are 203E, 203O, or 203X, the card is compatible with DoubleSpace. The latest revisions as of 6/20/93 are as follows:


The model DC200 controller card also has three EPROMs. If the number on the EPROMs is P20103E, P20103O, or P20103X, the card is compatible with DoubleSpace.
