Same problem. > I have sen similar problems. I am prety sure the problem is that the 1542 and the 2940 bios'es use different geometries. The solution is to be sure that you fdisk the disk, on the controller you will use the disk on, with the geometry that that controller will use. In line with my policy of "if at first you don't succeed, get a bigger hammer" the following. Install the 2940 and connect the disk. using ^A go into the SCSI Utilities and format the drive. boot off the install floppy and install. I believe this should work. PS. I have both a 1542 and a 2940U in my 3.0 current system at home.
