Sincerely? No.

But still worth trying.

Good luck then, mate!

Hi BlueAchenar,

I've bought a SanDisk 2GB SD card to try in the PCMCIA adapter.

I'll let you know how I get on with it.

Hi BlueAchenar,

This Dual CF to IDE Adapter V1.0 was one of the bits and pieces I received with my new A1200. I wish to get some CF cards to try it out with, but I have no user manual or other instructions for it and I was wondering if perhaps you would be able to tell me whether I could run it with just one socket populated or both, and if two cards are needed, do they have to be a matching pair?

Thanks,

prowler

I use a IDE 44 pin dual socket adapter on my A1200 with only one card. Works fine.

Yours is 40 pin. You'll need a 44 to 40 pin IDE cable and also a power cable for it.
I don't know if two cards will work with standard Amiga hardware/software. They might with IDEFix. I advise you to use similar branded cards though if you try.

I have IDE extenders and IDEFix '97 software in both my A1200's, so presumably this adapter will connect directly to the 'secondary' IDE channel, or won't it?

But, then again, I could use it in my PC.

I'll get a couple of matching cards and see how it goes.

Thanks,

Small update.

I've tried 5 PCMCIA->CF adapters so far. It made absolutely no difference in the outcome.

I've accidently put this a little on hold while I wait for the PSU cables. So here's the source code for the current (incomplete) driver.

Hello,

I quickly read through the thread.
I actually wrote a ATA/ATAPI device for the Apollo AT-2000 10 years ago.
What I remember concerning the 030+ compatibility is that you have to be very carefull with the DATA CACHE. Try to disable it to see if it fixes some of your issues.
I have the source code of the driver if you need it. It supports HDD in LBA mode up to 128GB, ATAPI CD-ROMs. It also has NSD + TD64 commands.
It does not use interrupts, so 100% of the CPU is used.

Regards,

Frederic

Thanks Frederic,

I'll look into it about disabling the cards' cache.
Your source code would be most welcome.

Just stumbled into this interesting thread, I am sure you must have the CF ATA spec which may help along with the specs you have. Just in case not, follow the link to the CF doc in this post of mine:

http://eab.abime.net/showthread.php?p=494684#post494684

Appendix 8 lists the diffs between CF-ATA spec and normal ATA spec.

Not sure if it is relevant, but maybe some of those different config settings in the different CF cards I mentioned in the post can be causing the problems too (but as the blizzard card is the difference, less likely I guess).
