I picked up an SE (M5011) recently. When I turn the power on, the screen lights up and I get the diskette icon with the question mark that is apparently looking for a boot disk. I have both a 20 Mb hard drive and a floppy drive in the unit. I hear no sound from the hard drive at all, and when I put a boot disk in the drive, it just ejects the drive a few seconds later with no real indication that it has tried to read the diskette. I get no error messages.
My first thought is that the problem is one common to both hard and floppy drives. A power supply problem was my first thought, but if it were the 12V supply for the drives, I don't think the floppy would be ejected from the floppy drive. I assume that it is not the logic part of the power supply, or I wouldn't get the blinking floppy icon with question mark. I'm beginning to suspect part of the logic on the motherboard that is common to both floppy and hard drives, but I begin to get lost in knowing enough to start. Can someone more experienced give me some suggestions as to how to proceed to diagnose the problem? Most of the things that I've found related to boot problems assume that the machine fails later in the boot process than my machine does. -- ----- You received this message because you are a member of the Vintage Macs group.
