Ultimate 1mb / Side 2

[Marius]

From what I understand (I read it very quickly, I'm at work) the loading speed is slower because of ATR mounting.

 

I thought only SIDE supported this... In that case you can't compare those two.

 

That's what I say: I'm not into comparing (I wrote: I'm not into a MyIDE vs SIDE thread) ...

The only reason I brought this up, was I heard Lotharek being so exited about the LOAD SPEED, while I thought: hmmm this is not so fast for a HD interface.

 

FJC explained why it is slower. And he posted his doubts about the actual speed of MyIDE (since I stated that on my system Numen loads 3 or even 4 times faster).

 

I will make a movie soon; I'm curious how much faster it is indeed. Perhaps it looks like 3 or 4 times faster, and is it just 1.5 x faster... no idea; have to check it

[Marius]

Ok watch:

@FJC you have to 'admit' that this is really a good performance.

@FJC you have to 'admit' that this is really a good performance.

 

It's faster than I remember any version of MyBIOS working in the past (and this is possible because finally the software is designed for harware which basically works), but really, I would expect no less than this from reasonably well written IDE routines, and the performance correlates exactly with what I said before about "real" partitions vs. the overheads of ATR mounting. Moreover - performance should be better under SpartaDOS X, and at least as good or slightly better again under SIDE / U1MB PBI. So the only surprise here is finally seeing MYBIOS running the hard disk at the speed we should all expect, after a decade or so of performance only slightly superior to the fastest serial I/O.

 

If anyone wants to post RWTEST results for comparable partition densities under the original MYBIOS, the latest MYBIOS, SIDE SDX soft-drivers, and Ultimate 1MB/SIDE (PBI), I'm sure it would make great reading.

Why not

 

SIDE (SDX partition) + VBXE2 in action

[w1k]

wow, thats like PC DOS

[candle]

Marius, i know this is a bit of a cheat, and comparing apples to oranges, but myide gives you roughly 31kb/s (average) and side 70kb/s

if you cut that down by 30% (side test was in 80 column mode, with antic disabled), then it would be still almost 50kb/s compared to 31kb/s

could you do the same test for myide2?

i'm curious

[atari8warez]

wow, thats like PC DOS

 

Yeah, and it's only 24 times slower than USB 1.1

Hi Lotharek. Did you say: booting atr without U1MB? Will it also work on previous version of SIDE made by Zaxon?

On the other hand: was the "PBI-enabled" U1MB ROM with SDX atr tools published officially?

Hi Candle,

 

Could you please give me a step by step instruction how to do this please. I am not a SDX user. The movie you saw was not SDX, but SpartaDos 3.3a disk version; using a double density partition (256 bytes/sector).

 

I think it is cool to show different configs and their performance next to each other, so if you can help me a bit further on how to do that test you mention, I would be glad to do it.

 

I also found out that newer CF cards (ofcourse with better specs) do give a (much) better result on the 100% same setup and test. When I use a 128MB card made in 2002, or I use a 2009 2GB card, there is a big difference in results. So when 'we' really want a good comparison we should all use the same kind of CF card.

 

It's great to see all these modern devices, giving such fabulous results. I get around 40KB/S on disk READ with the MyBIOS and SpartaDos 3.3a and double density disk. That is freaking fast, when you realize that most games aren't 40KB in total!

[candle]

Marius?

I don't know if there are any diffrences as far as this goes

you just turn your computer on, type rwtest and you're done

i don't know any myide regarded steps that might be nessesary for this, but i'm sure atarimax forums or Sijman will provide any help required

[Marius]

@candle

 

I meant: how to do that test with that 80 column and antic off you mentioned.

 

Could you explain that ... I would like to do a test which leads to useful results

[+Stephen]

If you are using VBXE driver, antic will be off. To also do this under SDX, make a batch file consisting of 3 lines:

POKE 559,0
RWTEST
POKE 559,34

This is off top of my head. The default value for location 559 may be 32, but I think 34 is correct.

[Marius]

Ok with MyIDE II and the BATCH file Stephen suggested here I got:

 

DOS writing: 38900.2971 B/sek

DOS reading: 61653.301 B/sek

DOS average 50276.799 B/sek

 

When I do not disable Antic I got this:

 

DOS writing: 28917.035

DOS reading: 45383.6799

DOS average: 37150.3574

 

This is with MyIDE II

 

Funny enough I got with MyIDE I (almost) same results. But... my homebrew myide does not want to operate properly on SDX. The AtariMax MyIDE I interfaces do work great with SDX.

[Marius]

I have to mention btw. that I did not use a SDX MyIDE driver! I got a DEVICE SIO /A in my config sys, and I use the MyBIOS in ROM.

 

I'm not sure, but is there a chance I will get better perfomance with the special MyIDE driver?

[candle]

chances for that are slim, you might get better results when using 512 bytes per sector

[Marius]

For some reason I can not (yet) get MyIDE II operation with the myide2.sys

 

But...

I got the MyIDE I working with myide.sys and apt partition with 512 bytes/sector bootable and everything.

 

Performance is incredible.

 

With ANTIC disabled:

DOS writing: 65352.4992

DOS reading: 90767.3599

DOS average: 78059.9295

 

With ANTIC enabled:

DOS writing: 48770.5217

DOS reading: 68075.5199

DOS average: 58423.0208

 

I hadn't expected this! It's a-m-a-z-i-n-g!

[candle]

remember whom to thanks for this

Jon is running low on peanuts

Hehe I know... I donated a few weeks ago already some peanuts.

 

Oh and one more thing: I succeeded now in getting the myide2.sys working on MyIDE ][ ...as expected: almost same results. Not so strange, since the IDE part seems to be rather the same, only executed by different 'logic' component(s).

 

Well to be exact... the DOS writing on MyIDE ][ is a bit slower; compared to MyIDE I.

 

But ok... It's rather cool this. I'm not a SDX user. I find it a very complicated dos, and it is (for me) so far away from what the 'original' Atari 8bit experience for me personal is, that I do not see me using it a lot. But I have to admit: this all looks very professional and well thought. I might give it another try.

 

The MyBIOS from Mr. Atari is more 'my cup of tea' .. It's a great combination with Ultimate 1MB with the MyBIOS in one of the OS slots.

 

But hey enough about this; this is a Ultimate 1MB / SIDE thread

[lotharek]

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

[+Stephen]

Sweet - anyone want to buy my original SIDE?

[Frankie]

The cases should be clear so we can see the board!

[TheNameOfTheGame]

The cases should be clear so we can see the board!

 

Omg no, love the atari grey

[Marius]

Very nice. I am definitely going to buy at least one ... I want to know how cool Side is.

 

I want to know a thing:

Is it possible in SDX to run a 8192 bytes ROM file that will act like a connected cartridge? I have the fabulous synassembler in Rom and I want to use that cart with my hard disk. But with SIDE (and also with Myide) the cart port is occupied. With ultimate 1MB it is easy to put it in a BASIC-slot bit I was wondering what the possibilities are on stock Atari ... Ofcourse there is the 'file-version' of synassembler but I would prefer SDX acting like there is a 8k cart attached.

 

So: is this possible in a way? That would be awesome.

 

 

[flashjazzcat]

I think that case is superb... a vast improvement on the original.

There's 256KB of external cart space on SIDE / SIDE2, although it's only been used for the XEX loader so far. If you flash your 8KB ROM image to the first bank immediately following the SDX image (which consumes the first 256KB of the flash chip), the SDX CAR: command should run it. Banked cartridges would be a different proposition, of course, since they'd have to use the SIDE banking. I did some experiments with the external emulated cart space a year or so back and it worked quite well.

[pixelmischief]

Can I order an SIDE2?
