IDE Express - speeds?

Well, it pops up with a message "you have both channels in slow mode - why did you buy an express?" when I have both jumpers on slow mode (funnily enough) so I think its working ok.  Certainly not reporting any cable problems.

I had exactly this same message and it turned out that it wasn't pushed onto the chip as well as I thought it was. I had to remove my indivision to fit it as they're touching when all is in place.

You also need to check that the small cable connecting to the splitter is fitted correctly, there should be indicators on the board as to where pin 1 (the red wire) goes.

I haven't tried any before / after speed tests, but I could have a go this evening.

Hi,

I bought an EB "IDE Express!" 4 way adapter and express module, which I have recently installed in my a1200.

I have a 1230/50 accelerator card installed.  

Basically I'm getting nowhere near the 5.0MB/s quoted on the ads etc.

I'm using a compact flash card and adapter.  The CF card is rated at over 20MB/s when tested on a pc.  However, when used on the amiga prior to the ide express it was getting a measly 1.3MB/s according to sysinfo, which I guess is to be expected on the original controller.

I installed the ide express adapter and it went up to 1.7MB/s.   I had some problems initially installing idefix that came with it (system would just hang on starting) but thats been sorted now - and sysinfo is reporting a bit healthier 2.0MB/s..

..is there anything I need to do to get faster speeds or is that the best my system can do?

Thanks.

These are the speed results I am getting with and without the ide express jumpers set.

SysInfo (Bytes/Sec)
Jumpers Set: 6,553,600
Not Set:     2,276,800

SysSpeed Raw Read (Ops/Sec???)
Jumpers Set: 4.83
Not Set:     2.79

This is a A1200 OS3.9, MBX 1230XA (50Mhz/33Mhz), 128Mb Fast. The disk is a Maxtor Fireball 3 ATA 133 (40Gb) running a 3Gb partition.
