Title: A1200 being a little sod.
Post by: tokyoracer on May 13, 2007, 12:26:45 AM
Hi there again Amigans,

I'm really having strange issues with my A1200 at the moment. It has no hard dive (for now because I still need to get some sort of Amiga OS onto it). That's not the problem. The problem IS however that booting up. Ever since I installed a Blizz 030 card (same as the one in my signature) it seems to have made my Amiga to act quite differently upon boot. The Board Diagnostic comes up with a line of info saying it's working.

It is as soon as you switch it on you have to wait several seconds (20-30 at least) for it to do anything at all. I put up with this fine right up until a few days ago when she won't even boot properly at all unless you hold down 2 every time (even then it doesn't do anything for a good 1/2 min). The thing is that it used to boot up with or without a Hard Disk fine, none of this holding down 2 stuff but it's started this recently and I'm getting annoyed with it.
Say I didn't press 2, what happens is even more strange! It takes AGES to do anything as usual but as soon as it reads a disk all it does it lights up the disk light but it's not reading it. Seconds later the 2nd floppy drive (external) lights up and does the same!!! :madashell:

What the hell is going on!?

I note in your sig that you hav the scsi kit also:

Is the scsi bus properly terminated?
Do the same issues occur with the scsi kit removed?

Regards

You have KS3.1 installed. Under 3.1, the wait time before the disk animation appears was increased to around 30 seconds. You will only notice this if you do not have a HD on your mobo IDE  socket.

There are devices sold that can change that behaviour by fooling the machine into thinking there is a HD connected so it stops waiting for the drive to report it has spun up.

Your holding down 2 is just disabling the 030 on your blizzard card. If the machine isn't booting properly with the 030 enabled, then it is possible your card has developed a problem . But in either case, it will still take 30 seconds to visibly do anything owing to your lack of HD. (Under 3.0, the spin up wait time was around 6 seconds).

Use a true 200W PSU and check the voltage !
I had nearly the same problem with a dying A500+ 65W Psu... (original A1200 psu is around 20W...)

I'm using an A500 PSU and is making no difference. My SCSI port hasn't ever been terminated but this has never been a problem in the past. Should I remove the SCSI part of it and see if the problems still occur?

Not to mention the disk animation NEVER appears unless you press and hold 2. Oh and once you do that only sometimes a yellow screen appears and the power light flickers a bit. Most of the time you have to hold it down for ages and no difference on the screen (but it still boots up eventually just it seems that it's pot luck if the yellow screen appears or not).

@tokyoracer

I can't help you, I think, but I'll say that I have had no such experiences with my Blizzard 030 (in A1200 running KS3.0 and WB3.0/1 software.) Other than the card there's only the floppy and a 2.5" HD in there, and I use a quite low output Amiga PSU - only about 40W I think.

The card does take a brief moment to do some things though, checking the RAM and possibly remapping the ROM.

If you end up suspecting that your SCSI kit is faulty, you could try sending it to me for extended "testing" ;-)
