A600 HD won't cold boot. Please help!

02 June 2009, 09:50

I have been working on this problem for a while now and decided to post this, may be someone has a solution. Here is my problem, I have an Amiga 600 HD and the hard drive went bad. I had a spare Toshiba HDD 2238B 200MB 2.5" IDE hard drive, so I replaced the old one with this. I then proceeded to low level format, format and then install the OS. After installation, I removed the floppy and restarted the machine. I then get insert a boot disk screen. I have Kickstart 37.35 so it should not be a problem. I removed the hard drive (Toshiba) and installed it a PC laptop and the HD worked fine, booted the laptop (after I formatted for pc and installed OS). I then reinstalled the HD in the Amiga 600 and re-installed everything and same thing happed (boot screen). I decided to do a warm boot (ctlr-Amiga-Amiga) and this time it read the HD and booted from it. I checked the HD and it seems to working fine. Decided to do a cold boot but to no avail. I still have to do a warm restart to make the HD work.

I have been reading some of the threads and they were saying to change the boot sequence to 4 rather than 0. I tried that and was still the same. PLEASE HELP!

This is really driving me nuts. Why won't it do a cold boot but would work after a restart? How can this be fixed? Any info would be appreciated.

Greetings,
I have a 2000 that can be a bit finnicky as to when and how it wants to start. I would suspect that Thomas will be able to help you better than I. In worst case scenario, if you can't get it fixed, a small circuit that does a warm boot some few seconds after a cold boot could be implemented.

Hello and welcome to EAB

. Stay awhile... Stay forever!

It could be that the drive is taking too long to initialise from a power up (cold boot) but works when it's reset rather than powered up...

Kickstart 3.1 has a longer timeout, IIRC... I don't think there's any way of slowing down the boot sequence on a 600.

Perhaps a reboot circuit is required then?

Very Simple solution to this slow spin up drive problem.

On the 44-way IDE ribbon, Cut the Wire for Pin 1, ie the first wire running along the bottom of the cable next to the Mobo's pin 1 identification.

When you Cold start your miggy you will still get the floppy requestor but performing a Ctrl-A-A will Boot the HD because it has now spun up, By cutting the RESET line the drive will not be reset during reboots anymore.

Get a KS3.1 ROM, the wait for disk spin up time has been increased.

Or

Get a IDE->CF adapter and a CF card.
