Setting up a GoldenGate 486SLC

trixster · 31 January 2018, 23:50

Hi,

I'm trying to get my 486SLC up and running in my A3000. I've installed the board, a trident vga card and the monitor master and all works ok. With cpu nocache I can get the board to boot ok. But I'm now struggling to get ms-dos 6.22 going on the on-board floppy. I've copied the 6.22 boot disk to a 1.44mb floppy using a pc but the GG just states 'Not a system disk' or something similar when trying to access FD1. I'm not sure if the pc floppy is working correctly because pin 5 on the floppy controller is missing!

It'd be simpler getting a set of ms-dos and win3.11 720k disks so I could just use the 3000's internal floppy.... so does anyone have ms-dos 6.22 on floppy and wouldn't mind uploading them as img files to the zone!?

MS-DOS 6.x is distributed on 1.44M disks too. You'll be better of using MS-DOS 5.0.

In order to make an MS-DOS floppy bootable, you need to copy some system files to it.
This is normally done during formatting by adding /S to your format command.

Format A: /S

Incidentally most A3000s have HD floppy drives, so 1.44 MB disks should be fine.

You learn something new every day! I absolutely did not know that, thanks!

So my 3000 has a hd floppy. That makes things much easier. I've setup an msdos boot disk and all works great!

You can also use the SYS command like SYS A: if you have already formatted the disk.

Just to tie up a loose end, even with pin 5 of the floppy drive connector missing the pc floppy drive still works ok now I've set it up correctly. I think pin 5 is just one of many GND lines, not a control line, so all seems ok

I don't know about that particular pin, but a lot of times they are missing on purpose, as a "key" for the cable to be aligned properly.

Yes I don’t know the Goldengate board (would love one!) but my A2088XT and A2286AT boards both have a pin missing for the floppy drive. Not near them at the moment so can’t confirm which pin.

DOS 6.22 successfully installed on a hardfile, just waiting for the 512mb DOM to arrive now!
