PowerBooks G3 Master/Slave question

[MikeatOSX]

Hi,
maybe somebody can answer this question.
I've fitted my PowerBook G3 Oldies Wallstreet and Lombard with Compact Flash card adapters for quick booting. That works great with fast CF cards.
I've also tried three different Dual Compact Flash card adapters, but the PowerBooks can't access any slave cf card, only the master card.

Note: this works with two ancient Amiga 1200 for me, but not with PowerBooks, which are several years "younger".

Can anybody explain, what's the reason?
I searched the net and found somebody, who declared to got it working with OS X (no earlier OS), but he didn't tell how.

I think this is caused by there already being two devices in the IDE/PATA bus, the hard drive and optical drive. If you remove the optical drive, do both cards appear?

 

[MikeatOSX]

That's an idea. I'll test this.

 

[MikeatOSX]

No, it didn't work.

Maybe the Powerbook's IDE controller just isn't able to work with the CompactFlash adapter properly to see both cards.
