Upgrading Blizzard 2040 to 2060 - Page 2

Iznougoud · 28 May 2008, 06:52

I don't believe he does when it comes to the 2040-card, since he hasn't - as mentioned previously - worked with them before. He doesn't even have an A2000 in which to test-run the card. Maybe we should all make an effort and donate one to him

. Anyway, my reasons for doing this isn't to get that more juice out the A2000 as much as - hopefully - improve compatibility, reduce heat and, all in all, make for a more pleasant ride. The extra CPU-power could come in handy should I find a NIC though, but it'll never become my main system for watching movies or listen to MP3s. Not with a 68k anyway. And what's a "classic" Amiga, other than one based around the 68k?

I do, by the way, have an old 486/100Mhz laptop (yes, 100Mhz. Didn't know they got that high before I found that laptop). The RAM-sticks in that laptop should be able to handle both 66Mhz and 80Mhz. Shouldn't they? And the same would in my opinion, to some degree, apply to RAM-sticks from 468/66Mhz systems..

Edit: Come to think of it - when did Compaq introduce the FSB and multiplier, might have been somewhere around the 66Mhz-mark..

Intel introduced clock multipliers with the 486, called DX2 and DX3. You have a 486DX3 there, the FSB is 33MHz. That's the highest FSB for Intel made 486. AMD and others made models with 40MHz FSB (upto 120MHz internal). I'm quite sure that are the highest clocked ones.

Iznougoud · 28 May 2008, 13:57

Still. The highest external frequency for a 486 would be 40Mhz then, which in essence blows my theory out of the water..

Edit: All is not lost however. At least I learned that my laptop's probably packing an Intel 486 DX3 ..

musashi5150 · 28 May 2008, 14:05

There was also a 486DX4/100 of course. I used these at college before the first run of Pentium systems arrived.

http://en.wikipedia.org/wiki/Intel_80486DX4

Edit: This is what you were referring to as 'DX3'.

ganralf · 28 May 2008, 18:35

Oops, yes DX4 not DX3.
Thx

Zetr0 · 28 May 2008, 19:32

It not so much the RAMS frequency, it is the RAM latency that will deem its compatibility,

I do not know the cards memory controller logic propagation time, this will effect on what speed you can make use of on the system, 50ns / 60ns / 70ns etc.

From the age of the card, i do doubt that 50ns would be achievable as there is too much glue / logic in the way of memory access, in truth it will be touch and go if 60ns would be possible.

To be honest, i would side with Alexh on this, I seriously doubt an 060@ 80mhz would result in successful operation, infact i doubt it would be possible, since you would need atleast 60ns or better latching (r/w) times for the RAM, However 50mhz 060 would poodle along quite nicely with 70ns memory

Yeah, 80 MHz RAM speed is a huge stretch, but the (rev 6) CPU will quite happily run beyond 80 with the memory divider set to 1/2. 1/1 would be possible with a more modern RAM controller (like the CT63).

"Intel named it deceptively during litigation with AMD over trademarks"

Iznougoud · 01 June 2008, 01:14

Finally got an answer from FrankBrana. And according to him "the logic array chips contains both code for 040 and 060".

He also stress that "once you perform the hardware upgrade /---/ you MUST boot the machine without any memory on the 2040, to let the PALs update itselves to the new cpu".

Thought someone else might like to know. The part about booting without any RAM was news to me, anyway. So it was a good thing I asked.

Zetr0 · 01 June 2008, 02:29

Thats very interesting!

Jope · 01 June 2008, 07:20

Make a writeup about this once you've done it and I'll add it to a suitable sticky thread. Same thing if any one's documented cyberstorm upgrades.

Interesting!!

So you're going to hire Per-Gunnar for the CPU swap?

Intel made a 486 DX 50Mhz (before the dx2, there was a dx25, dx33,dx40 and dx50.

The DX50 was hideously fast at the time - as it ran the bus at 50Mhz (utterly out of spec) but often left the dx2-66 for dead due to everything else running faster. (I used to have both).

There was also a 486 @ 133Mhz ("DX5") made by AMD. They marketed it as 5x86 - as they claimed it performed on a par with the 586 Pentium-60Mhz that were around at the time.

i need a 2 files eprom 8.5, please, where can i find them ?

thankyou for your help.

Saya

sayasupacrew · 10 October 2009, 17:12

We have performed the upgrade to 060 but the frequency
is always divided by 2 with a 50 Mhz xtal. And with 66, yellow screen.

We need the last firmware 8.5, because we have the 8.1
Please, upload the two files or send us the two eproms 27c256

But, we have the firmware from a Blizzard 1240/1260 and from
the SCSI kit : the same for the 2040/2060 ?"

radzik · 14 January 2010, 17:32

So if I want upgrade Blizzard 2040 I must upgrade eproms too?

@Radzik

As I told you already I never did Blizzard 2040 upgrade to 060, but from two links you sent to me there is nothing mentioned about upgrading EPROM's.
Two EPROM's 27C256 are indeed mounted on the board, but they are OTP (One Time Programming) devices and cannot be re-programmed.

radzik · 15 January 2010, 12:57

World is small.

I think that update is not needed, but sayasupacrew disturbed me.

sayasupacrew · 08 February 2010, 20:54

I' use my 2040 ( up060 ) with firmware 8.1 and to have now, me is not of problem with its use.
-----------------------------------------------------------------------------------------------------------
configuration:

Amiga 2000 6.2 ECS
Scandoubler & filcker fixer electronic design (on video slot)
one megachip (add One mega octects in chip ram)
Cybervision 64 3D
Blizzard 2040 (up060)
2 chinon floppies

1NOM155 · 28 November 2015, 00:09

I know this its a old thread, I like if anyone find out how to upgrade / update DiagRom?
I may buy a Blizzard 2040 for later upgrade to a 060, but I like to know if that issue is easy to fix

For curiosity sayasupacrew what version of Blizzard 2040/60 do you have?
