The CF adapter you are using looks a little like the one I plan to buy, which I have pics and links to here:http://www.atari-forum.com/viewtopic.php?f=15&t=14895#p127743
Can yours work as a 2.5" 44pin Master and 3.5" 40pin Slave? What model is your CF adapter and where did you buy it from? I am hoping to slave a CD-ROM or writer to my STe, and I am still trying to figure out what software combination I will need to achieve this.
Usually IDE-CF adapters have Master/Slave selecting jumper, so it is not issue.
For CF best is to buy some Sandisk.
I need to try it with some CD or DVD ROM... It should work with Hddriver after reconfiguring it in Hddrutil...
Although, I don't see idea to write CDs with ST as good.
Also, don't see much perspective in 16MB expansion of ST. It is possible to use max. 14 MB of such RAM, as TOS and HW takes 2MB address soace. Bigger problem is that there is no SW which can benefit of that RAM size... Mint is not really for 68000 CPU, which lacks (paged) MMU.
But 16MHz speed-up seems as good idea...
