AmigaOS 3.1 upgrade on my A4000
« on: February 22, 2006, 02:41:43 PM »
I'll start off with more praise to AmigaKit as I got my 3.1 ROMs and 3.1 OS in the mail yesterday.  Everything was packed very well and the included instructions were easy to follow.  I've had good experiences with both AmigaKit and Softhut with AmigaKit having a slight edge partly because of their wonderful support on these forums.  You guys will be getting more orders from me in the future as soon as I explain to my wife why I need more Amiga stuff.  :)

I took about 45 minutes disassembling my A4000 and pulling out my 3.0 ROMs since I didn't have a chip extractor and had to use a combination of my small Swiss Army knife and a small flathead screwdriver.  I then took about 15 more minutes getting the new 3.1 ROMs in.  I was very methodical and made some drawings of the machine as I went.  I did learn a lot about the insides of the A4000 that I didn't know before.

The ROM upgrade went off without a hitch.  Well, I did bend 2 of the pins on the old U176 3.0 ROM chip taking it out.  I'm gonna pick me up a chip extractor.  :)

Computer booted up fine and the correct Kickstart version showed up in Workbench.

I then set about installing the 3.1 OS.  My computer came with OS 3.0 as well as Kickstart 3.0 and was working fine.  It also came with ASIMCDFS 3.0 for the CD-ROM drivers and was working fine.  The install went off without a problem until the reboot.  After rebooting the computer would Guru, (I know Guru is gone but I'm nostalgic that way) as it tried to load the ASIMCDFS drivers at boot time.  It did this every time.  :(

Luckily I had not loaded much on my A4000 yet so I put in the 3.1 Install disk and formatted my 4GB drive partitioning it to a 1GB OS section and a 3GB Work section.  After rebooting everything worked fine except the CD of course.  I had the floppy disk with the ASIMCDFS drivers and then reloaded them.  Did the Novice install and took all the defaults except my buffer settings, I put them on my HD1: partition, rebooted and it worked fine.

So now I've got 3.1 all around on my A4000 and it works just fine.   :)

I just wanted to relay my experience with this in case anyone else runs across a similar issue.

Now to put AmigaOS 3.5 on.   ;)

I already bought 3.5.  I thought it was a pretty good price from AmigaKit and now combined with my other Amigas I've got OS 1.2 through 3.5.  I thought OS 3.9 needed more RAM.  I've only got 16MB Fast and 2MB Chip on my 68040/25.  No graphics card either.

Would that be powerful enough to run OS 3.9?
