I have been working on a problem for the past few weeks and I haven't been able to find a solution. Essentially, I can't get my 5150 to boot from a Gotek drive with FlashFloppy except for 180K disk images (i.e. IBM-DOS 2.11). I have read in the forums that even newer versions of DOS should run on the 5150. More details below.
The situation:
I recently picked up my first IBM 5150. (Woohoo!) I have gotten it to a working state (except for this problem) by replacing memory, cleaning and restoring drives, power supply, etc. It has The BIOS has the IBM part number of "1501476" printed on it which I believe is the third-gen from 1982. It came with two Teac FD-55BV-36-U which seem to be working fine. Is also has a Seagate st225 hard drive which I am not using for now. However, I have no software or other older PCs that I could hook one of these floppies to in order to make some physical boot media.
- I connected a Gotek drive with FlashFloppy firmware as the drive after the twist replacing one of the Teacs.
- I can boot IBM-DOS 2.11 which is a 180K disk image.
- I can format a physical disk to 360K on the Teac drive after booting into 2.11.
- I cannot boot any image larger than 180K (i.e. 360K or 720K) from the Gotek. I get "Disk Boot Failure" from IBM-DOS 3.3 and "Non-system disk ..." from anything newer than that.
- The system scans the Gotek drive like it's reading it, but then returns the errors above.
What I have tried:
- The system originally had a PC's Limited clone of the standard IBM floppy controller. I switch this out with a standard IBM one.
- I have checked the switches on SW1: 7 is OFF, 8 is ON.
- I have checked the cable and the Gotek drive on my TRS-80 M3. So at least I know they are working if I have the right settings for the right machine.
- I have tried custom IMG.CFG on the Gotek with settings for 360K drive geometry explicitly stated.
- I have tried .hfe versions of the floppy images using HxC floppy emulator.
- I have unplugged all other cards in the system besides the video card and floppy controller.
- I have tried multiple boot images from multiple versions of DOS (both IBM and MS). I have gotten most of these from winworldpc.com.
Does anyone have any other ideas? Can anyone confirm that they can boot from a gotek drive on a 5150 with 360K images? If so, were you using HxC firmware or FlashFloppy? I would appreciate any suggestions. I have learned a lot from this forum over the past few weeks!
Thanks!
