1040ST only boots properly with disk in drive

[shazzner]

So the other day my ST was turning on but giving me 3 bombs (bad address error), I opened it up and checked everything, reset the chips, cleaned up a few bits. Thankfully it'll boot games and to TOS but only if I have a game disk or system disk in the drive respectively.

Without a disk I'll just get a white screen and it seems like it tries to seek a disk repeatedly.

Any ideas as to the issue?

Desktop takes about 40 seconds to come up without a floppy in the drive. Try a blank formatted floppy to speed up the desktop appearing.

Well I could have sworn it booted with a logo and memory test, but I guess it's been long enough that I got it wrong. It eventually booted just fine.
Sorry for the topic, I guess I just panicked haha

<TOS104 is just a white screen , >TOS1.6 (STE) boots with the logo.

My STE doesn't have a logo. That's a tos 2 thing.

I thought that but a thread on AA a guy said logo comes up on 1.6. I've not checked it myself.

Noooo I said:

Yeah, 1.6/1.62 doesn't show the logo or do the RAM test, it's TT/Mega STE/Falcon TOS versions that do that. 1.6/1.62 do the rainbow Atari logo under Desktop Info though.

So if it's a TOS 1.x machine you'll get the white screen for 40 seconds, then the desktop.
