44-pin IDE Interface to Secure Digital

[galem3]

Hello,

I need your help because I bought this :
http://www.vesalia.de/e_sdide44adapter[6375].htm

the SD card was formatted with Winuae,
I installed the Workbench 3.1 on it, but when i put the IDE to SD on my Amiga 1200, it wont boot.

Thank you to help me

Probably a silly question but did you mark it bootable in hdtoolbox? Getting my converters bought at deal-extreme this week hopefully. Got a CF 4GB with ide converter from ebay last saturday will try it out tonight if it needs something special., but bootable thingy miht just be it.

The hard drive needs to be partitioned with the MAX TRANSFER value of 0x1FE00 and must not have a boot partition larger than 2GB.

Make sure in WinUAE you are using A1200 Gayle IDE emulation and kickstart scsi.device and not high-level disk emulation and uae_scsi.device. This is the only way to ensure that a disk bootable in WinUAE will be bootable on a REAL Amiga.

The second silly question is did you plug it in the right way round?

Also we've found some CF Cards/Adapters require a soft reboot (CTRL-A-A) after powering on to start booting. Maybe its the same with this SD adapter...

Hello all,

I'll try formatting the card again with all the information you gave me

thank you for your help

I know about the 4GB limit(just installed a 2.5" 20GB in one of my A1200's) but is the 2GB limit AUE limit or does a 4GB CF formated at a real a1200 work normally? ANyhow I'll find out in about an hour for myself thanks for the headsup.

Hi mate

Jus to comment.......

I read this description in the seller site:

- SD and SDHC memory card slot
- 44-pin IDE interface to connect a 2.5" IDE cable
- Power supply via IDE interface
- Bootable
- Hot swappable
- Dimensions: 53 mm x 42.3 mm

Amigas, as I know, aren't hot swappables. I you try to make a hot swap it's possible your damage the adapter or the card (or both).

Best wishes

AFAIK FastFileSystem and scsi.device which ships with KS & WB3.1 have a 2GiB limit for partitions and a 4GiB limit for devices.

That means you can safely have 2 * 2GiB partitions on a 4GiB device under an unpatched 3.1

Thanks, i bought about 4 off those from deal-extreme some with 8GB and some with 16GB limits. Hot swap in a A1200 is not an issue since i have to unscrew the little monster. Hmmm unscrew and amiga maybe that's why my ex gf left me

Hiya for your information,
I just installed a 20GB HDD in one of my Amiga's kick 3.1 does accept <4GB partititions, so i made a 4095MB and it works, the spare odd 15gb is a work partitition. You will need os 3.9 (maybe 3.5) to actually see the 15GB one

*edit hmm 10 post within one day (let's say 5 hours) I'm not lurking anymore. But you ppl keep me away from my amiga projects!! luving it

@Alexh: this theory fall over the ground some time ago.

You can do a 4Gb partition, but the problem will be the programs. Most will refuse to install arguing there's not enough room to install, if a validation problem occurs the ROM automagic fix will take years (literally!) and other annoying problems.

A boot partition over 250Mb was never needed for 68k Amiga OS. Just OS4.x needs more than this.

Oh, the correct Max_Transfer is 0x1FE00 (128kb minus one byte), not 0xF00 (3840 bytes).

Its been a while but wouldn't 128 KB -1 one byte l-word alligned be 0x1ffc?

so atleast the transfer might be 0x1ff0 ?just a few bits more but might make a difference

 

[rkauer]

1FE00 = 130560 = 127,5kb

128kb - 1 = 1FFFF.

So, 128kb minus 512 bytes, sorry.

@Misser

As rkauer saids, 0x01FE00 is the best option and most compatible

I stand corrected, I'm still a bit f..cker something left over from my c64 days I guess. But its like the saying says, never to old to learn some new things.
Tack ehhh thanks, I don't know why I'm in swedish mode again
