In Finland, other bits of Scandanavia, I hear you hit each other with birch twigs, dance naked through the snow, have sex, and Sauna.

Not necessarily in that order, and now you tell me you only do the above while under the influence of alcohol anyway.

Sounds like you'd fit right in here, to be honest. Less of the subzero temperatures, of course.

[Locutus]

Sounds all accurate enough.

A little more speed for the same clock rate

That's a fair jump, optimized ram timings? What if you soft-kicked another kickstart, would you gain a little with all the libs in 32-bit fastram?

@plasmab, just saw your Dave of EEvlog imitation and it did make me laff, your funny dude ....and clever ,would love a CD32 accelerator

Maybe. But for now i'm just looking at the CPLD stuff. I shaved a dumb clock cycle delay i had in there. 4x is about right now at 2 times the clock speed and 2 times the bus width.

Heh. Yeah i need to do a Louis Rossman impression video. How to do it without upsetting Louis. Maybe when i move into the new lab...

Its as authentic EEVBlog as i could make it.

I need to figure out what to do about autoconfig ids.

Short explanation - partly.

Long explanation - some libraries live in kickstart. Some don't. In theory you can pick and choose which you want preloaded into fast RAM. LoadResource command lets you preload individuall libs, devs, fonts and catalogs to RAM, from disk. Relokick or similar utility lets you sideways map a different ROM. I think LoadResource was introduced in OS2, not sure about about that.

Actually getting a startup-sequence right for a given set of applications is quite a struggle, but you can do that or more with most any kind of fast RAM, not just accelerator cards with fast RAM like this project. It's very handy to have ROM shadow on a jumper, saves you (the user) writing the code, true. But maybe not necessary to get to work.

IDE = It's Done Eventually.

Actually it's not that straightforward for an A500 - I guess you are going to have to pick a minimum Kickstart to be compatible with. 1.3 was the first with autoboot. Not many 1.3 Amigas had hard drives at the time, and limiting it to a 2 or higher might save you some headaches.

I guess after that, it's a question of using Autoconfig so that the A500 has some idea of how to access the drive, from the minimum KS selected, using the libararies and device drivers available (typically SCSI.device, also ATAPI.device).

Most inbuilt Amiga IDE support is crap, and depends on an A1200 or A4000 design. Both 3.0 and later. But, the firmware for the controllers isn't operable in A500 V3 and higher ROMs, because the A500 does not have such a port built in.

The commercial IDEFIX has quite a bit of driver support, but it's commercial. Available in IDE97 and IDE99 flavours, trying to get support for 64-bit and also boosting transfer speed (the A1200 controller was only designed for one drive). I'm not saying make it dependent on the driver (not a good move) but studying those might give you some insights into what you need to do to make your IDE port work well on an A500.

HDToolbox is of course the standard CBM utility to prepare, wipe, and partition drives. Usually with "Quick" formatting, as the standard format command is hardware limited to partition size. That's about as much as I can say with confidence - and is probably far less than you already know.

even with all the downsides, Gayle style IDE is probably the easiest solution.

If memory serves there are two people who can allocate you an autoconfig ID. One of them is Olaf Barthel, who allocated one to me a couple of years ago for Minimig tinkering. I can't remember who the other is, but I think whoever it is allocated Majsta's ID for the Vampire project.

[Locutus]

I think Thomas Richter might be the other person to ask, atleast he will know.

In essence you want a ID that the guy who updates boards.library will accept :-)

[plasmab]

Thanks guys.

I recognise that name. Is Thomas involved with MiST?

In other news I fixed the mouse flicker and she is up to A3000 speeds.



Frontier runs sweet as anything.

Great jump in performance, BTW. Now it's on par with the Furia.

Yup, that's the combo. I take it you switched on Burst mode?

Thank you SO much. Clearest, most straightforward description I have ever read on the subject of Autoconfig and manufacturing hardware IDs. From anyone, anytime. And it's Hyperion, makes sense they're the people with their finger on the trigger.

Surely it goes faster? I saw them getting it up to 40Mhz or so.

Well.. All RAM access is 2 clock cycles. I think i could get a tiny bit more out of it.
