Amiga 3000 kickstart question

[alexh]

The Superkickstart3.1 file is available in lots of places on the net. A regular KS3.1 (for A3000 with SCSI support) with the bonus code tagged on the end.

The file (Kickstart) just replaces the 2.x one ( WB2.x:Devs/Kickstart) and next time you reboot voila KS3.1.

The downsides over a hard ROM are: you loose 512Kbytes of FastRAM and you cannot use an accelerator.

P.S. If you are incapable of identifying and unpacking LZX files, you probably shouldnt have an Amiga at all, not to mention a fiddly A3000 KS1.4 ;-)

You can use a Blizzard 4030 @ 50Mhz ... and with softroms you are able to use Commodores Unix for the A3000.

I tend to doubt this, ( can't say for sure since I never
tried it).

I can't beleave how much erroneous info is floating around
about these particular Amigas. I've had mine since 1990,
(bought it new). I guess the reason for all the bad info
is there are really not that many of them around.

I think Jeff would know... seeing as he has one!

Yes. The issue is that the 1.4 ROMs are hard-coded to the 030's MMU. 040 and 060 accelerators won't work because their MMUs function differently so that the ROM image can't be softkicked. Any 030 accelerator should work, but I think there are only 2 kinds, the Blizzard being one of them.

and with softroms you are able to use Commodores Unix for the A3000.

Unix doesn't make use of any special 1.4 ROM features as far as I know. Whenever I boot it, I need to kick in 2.04 first and then use the boot menu to boot from the Unix partition.


Also, I always thought ExtractKickstart was for pulling an updated kickstart off of a SuperKickstart disk, not for pulling one from ROM...

@Bonami-

However, i *actually* noticed the 'slow' speed of my A3000 with KS3.1 ROMS - as reported by Sysinfo.

When i first got my towerised A3000 five yrs ago - all the way from Germany - it came with 2mb chip + 4mb fast, but due to my lack of experience, i inadvertently screwed up the zip rams Thereafter i cold-storaged my A3000 (i mean can you run any program productively with a 2mb amiga?)

Recently i bought a Fastlane pop'd with a whopping 64mb ram (the max is 256mb but you'd have to be extreme lucky &/or rich to get this kind of ram modules), and got all excited to revive my A3000.

Indeed the extra ram speed up the operations on the A3000 (plain WB3.1) tremendously. So i installed Sysinfo for the 1st time on this system to check. The report was a shock... so very perplexing! altho in reality i'm very happy with the RAM boost.

Perhaps there's some flaw with the Sysinfo?

Why would you think this is due to the kickstart?  It's actually due to the different speed of access to your RAM.

For fastest to slowest access time...
FastRAM on accelerator card
FastRAM on motherboard
FastRAM on ZorroIII
FastRAM on ZorroII
RangerMem (A500 bay)
CHIP RAM

The fast RAM that was on your motherboard would be faster access than the fast RAM on your ZIII board, hence the overall performance loss of not having RAM on the motherboard.  

I've never heard of a ROM having a slower access time than the 1.4 SuperKickstart.  In fact, either way, your ROM timing is going to be exactly what you set your motherboard ROM timing jumpers to.   :lol:

If you really want to boost performance on ROM calls, like others have said, get an accelerator and blizkick your ROM to the FastRAM on your accelerator.  That'll give you a speed boost.

Having to clock down to 16 MHz is b*llsh|t - there are jumpers to adjust ROM speed (J151/152) from 160-280 ns - they can't be that slow (at least original ones).

@ilwrath
Actually ranger mem and chip mem are exactly the same speed. You can also find ranger mem in A2000s with OCS Fat Agnus (512 KB chip).

Getting a softboot Kick3.1 is easy!

All you need is a A3000 WITH Kick3.1-ROMs and the WB3.1 Install-Disk.
In directory c: you can find the "extractkickstart" tool.
With this tool you are able to create a A3000 superkickstart with kick3.1.
With this superkickstart you are able to boot Kick3.1 on a softboot A3000.

YES, COMMODORE RELEASED A KICKSTART-RIPPER WITH WB3.1 !!!

 :lol:  :-P

And what arguments should be used? :-D
extractkickstart ?

necrobump.

I believe this tool only allows you to RIP a Kickstart from a SuperKickstart disk to a file.
