In response from certain users whom i will not mention here (bigmac, Duce and LoadWB) complaining about the non Amiga content on Amiga.org i have started this thread that will contain Amiga content only and all social talk is forbidden.
So er, how's everyones harddrive doing?
:p

I'll run with this.

Kinda slow, actually. Anyone got any tips for a Compact Flash drive in a 2000 on a 2091 controller? Could bad termination be slowing things down? We're talking transfer rates in the 90K/s range.

Nice trolling.

You using an accelerator? 2091 only has SCSI, right? What's your converter?

Yup, got a A2630 with heaps of RAM. 2091 is SCSI only (also with full complement of RAM), and driving a native SCSI card reader.

Now c'mon, did i actually mention your name? Brackets don't count :quickdraw:

90k/s sounds a little slow to me. I haven't done any SCSI->IDE(CF) work, so I can't speak on the performance of the converters. I do know from experience that different cards perform better, even within the same speed class. Have you used something like SCSI Bench to test raw throughput and CPU load?
-
Wondering this myself. I wanna go a Mechy Adapter route, but I'm still running stock 68000 in my 2000 with a 2091 with rev4 WD chip and 6.6 roms. I dunno if my Rev4 chip and barebones is up to the task.
BUT I gotta think anything is better than my 40MB SCSI drive from 1990...
-
90KB/sec is very slow. I've got a GVP HC+8 card with a Guru ROM, connected to Mechy's native SCSI CF card reader on my A2000. I'm using a Transcend 16GB 133x CF card. I'm getting ~1.5MB/sec transfer rates on it regardless if I'm in 68000 or 68030 mode.
I had to disable synchronous transfers on the CF reader otherwise it would randomly lock up when copying large amounts of data. Disabling synchronous transfers didn't seem to have an impact on performance though.
The GVP card does SCSI DMA directly into it's onboard ram, I'm not sure if the A2091 does the same.
If you can, get a Guru rom for your A2091, it made a huge difference to my GVP HC+8 in terms of stability and performance. Unfortunately the adapters that the Guru rom plugs into are difficult to come by. The rom image itself is available on Ralph Babel's hompage http://babel.de/amiga.html but it won't work without the adapter.
Sorry I can't help you more..

I`m about to buy the IDE2CF adapters (CF card included) from AmigaKit, one for a barebones A1200 and one for my A4000 (CSPPC/060@50). How do they perform respect to a standard IDE HD?
-
On my A1200 the CF is very quick. You are limited to the ~2MB/sec of the IDE port on the A1200 motherboard. What makes it quick is there is no seek time to speak of on a CF card, so it boots up in no time. My workbench is ready before my monitor has warmed up enough to display the image if I do a cold start.
Once in Workbench, it definitely "feels" a lot faster when accessing files and folders, however if you are going to copy a lot of files or large files, it will still take a while due to the 2MB/sec limit of the IDE port.
Just a warning if you do get an accelerator for your A1200, some CF cards don't initialise in time when you cold boot the A1200. It'll give you the insert floppy screen. Usually a Ctrl + A + A will allow it to boot, but it is irritating when it doesn't want to boot first time.
My Transcend 4GB and 8GB 133x cards boot fine on an accelerated A1200 but my Trancend 16GB 133x card won't cold boot, I have to Ctrl + A + A to get it to boot.
Unfortunately I don't have an A4000, so I don't know if it'll show the same symptoms of the A1200, especially as you have such a fast accelerator for it.

Hard to get a picture of just the adapter. I wonder if its just mapping one chipsize to another 1 to 1, or if there is some logic on it...

The adapter has a PAL to do some sort of address decoding as the GVP/A2091 card only has enough address lines for a 16KB ROM (27C128). The Guru ROM is a 32KB chip (27C256). I have tried to copy the PAL but naturally it has the copy bit enabled so I couldn't copy it.
It is frustrating as the Guru rom is no longer commercially available. I'm always happy to support any hardware vendors such as Jens and Ralph but when they decide to no longer support a device, they should make things like the PAL image available to everyone so that we can at least make the adapters ourselves. :(

Been having issues with my CF HDD. Though a recent format and reinstall on CLassicWB Full and PFS seems to have sorted it.

I did not realize that the chip was made by Ralph Babel - there's no chance we'll ever get that adapter array information.
I can get 7.0 ROMs for my card - its the rev 8 WB chip that is the hard one to find.

Has anyone else tried the latest Indivision ECS firmware with the 800x600 super display yet? Works great with my LG LCD.

Have you tried the utility "vb2091" on Aminet? It really made a big difference for me when using an an A2091 and a 68040 accelerator with 32-bit RAM on board. Helps with the DMA issues.
aminet.net/package/driver/media/vb2091
I eventually bought a GURU Rom from my A2091, which was also good, but it was damaged a few years ago through some sort of electrical fault and I don't know if anyone can repair the GURU ROM (I guess the chips on it would have to be replaced and flashed with the GURU ROM code - I have the bin images for these chips but cannot burn them).
Here's some good reading on the A2091 and accelerator RAM DMA issues:

Mechy sells them on his website, not too expensive either, it's the AMD version which is the same as the -08 WD version.

Sweet! Thanks a bunch!

It's a pleasure! :)
I'll swap my Guru rom for the regular v4.15 GVP rom and set my A2000 to 68000 mode and do some benchmarks for you. I know it's not exactly the same as your A2091, but it'll at least be an indication of what you can expect.
The main reason I went the CF route is that with all the expansion cards and 7200RPM SCSI drive in my A2000, the A2000 was getting REALLY hot. I could barely touch the HDD. After swapping it for the CF solution, it was running MUCH cooler but it also made my A2000 much faster. Not in terms of raw speed, but workbench operations are much snappier, opening a drawer with lots of games in it is now much quicker.
I'd definitely recommend going the CF route over a normal HDD.

I noticed a huge speedup in my A4000 when I stuck a CF card in it, and just on the motherboard IDE port, which everyone poo-poohs as slow. Right now I am waiting to redo the caps on the mobo for her, so the 2000 is getting some love, since its recap is and was easily accomplished with just an iron and some solder wick. There's something to be said for wide open and easily accessible componentry!

What about Mask and Max Transfer rates for a 2091?

While not following the rest of the thread, I find your question interesting.
I'm not that familiar with this piece of Jens' hardware.
How well does it work and what software is compatible with the 800x600 display?
At one time I ran PCs at this setting and it was adequate.

It's only workbench that runs in 800x600 setting as you need the monitor settings to make it work. It certainly makes navigating though larger folders easier as you can really open the windows to see more stuff. I have the links laying around to a german forum with the superdrive(think it's called that) and the latest firmware. It however does eat memory if you have fancy workbench effects going. So I use the oldschool wb 1.3 theme on ClassicWB full as it looks good and keeps things zipping along. :)
As for the device it's self. It does an adequate job. I have no reason to complain for what I use it for.

Thanks. I really like your A600 setup. Looks like a nice, compact, yet powerful system.
Jens still has some 42MHz accelerators for the 1200 that also look attractive (if he ever gets around to finishing the latest flicker fixer for that machine).
Hey, that's not too social, is it?
-
I had the GURU ROM for the GVP 4008... made a huge difference, I could not get my CD-ROM to work reliably before that.

I have just finished putting a HxC into it. So I no longer have to rely on disks at all with it. Sad in one way but makes life easier in another.

I know the feeling. I have 1.44 drives in two of my PCs, but they get very little use.
A few days ago I did use one to hold video card bios files for ATIflash.
But I booted the system with a CD and the latest version of ATIflash was also stored on CD because it was too large for the floppy.
-
I have several A2000 toaster setups and use them for titles saved to DVD burners, I am tired of the same old fonts to display, looking in old mags I see that several font packages where sold. I check E bay but most of the time the disk are part of a pack of 100 disk sold as blanks, might be some thing or may not. I am looking for a font package for the toaster or any Dpaint program. something flashy not the large yellow font I use. also because I am a rule breaker, how about them Giants? SB 2012...

it was a tough decision to not have a proper floppy drive in the 600. But as a gaming machine first and everything else second I needed to think of the longevity of the system. Which meant going for WHDLoad and HxC. It's awesome, don't get me wrong, as the HxC does all the proper click sounds a real floppy drive would do. But it doesn't have the same feel now. If you get my drift.

I have talked to ralph about this at one time, and because places like softhut list them but do not have them,ralph won't release the code because he says it would undercut vendors. I explained that i contacted softhut and they don't have the guru roms but this did no good.

Aren't you an Amiga Vendor? Do you not qualify as a distributor?

Hi,
Been trying for about 18 months now to get a CF and a CD drive working together, I don't think it can be done, something there is not allowing something not to talk. Anyhow if I use the CF drive alone it works great. And Paleese don't say I need a buffer for this to work, I have a 4 way buffered ide interface.
This is what makes the Amiga fun

I was just thinking. Would I be able to get Amix working on my 600 with Accelerator I have installed?

I don't think so. Amix has very limited hardware/driver support. It might start to boot, but it probably won't recognize the onboard IDE as a 2091 or the A3000's onboard SCSI, so you'll be without a hard drive. I think there's a good chance it won't recognize the accelerator's RAM, either.
-
Fair enough. Just thought I would ask as it seemed interesting. Maybe I could emulate it?

That and the Voo-Doo of SCSI. If you're trying the CF and CD on the same chain, a thought comes to mind: master/slave configuration, but not your settings -- maybe the CF or its adapter doesn't like having a slave present. I've seen that in the world of old IDE hard drives. If they're on separate chains, then your guess is as good as mine. Anyone have an IDE protocol analyzer?
-

WinUAE might be able to do it these days. I recall that Amix needs an MMU, which WinUAE didn't emulate for a long time, but I think it does now. And it definitely has 2091 emulation.
