I see that this thread has been inspiring....
In the interests of completeness, however, I will report finally that I simply could not get the internal CF drive of which I wrote above to work in the 2400c. The CF drive was recognized sporadically, and was formatted with Silverlining as well as with HD Setup on at least two occasions, but it seems that the 2400c lived up to its reputation as fussy here too, in that it just did not want one of these alien things in its innards. I did manage a partial system install several times, but it aborted on each occasion mid-way through, telling me that there was a problem with the drive.
Thus, to begin at the beginning again, a 2400c with fresh, definitely charged backup cells and a working main battery exhibited the following characteristics: 1) an ATA-100 Fujitsu 30GB drive mostly worked (known scsi target mode incompatibility with large drives in the 2400c excepted), but there was a serious failing in that the machine would not awaken from sleep with this ATA-100 drive installed; 2) an IDE-CF with 8GB CF card set first as Master and then with no jumpers at all would not work in the 2400c. Master setting worked occasionally; with no jumper it did not work at all. I did not try Slave, having run out of patience. The internal IDE-CF adapter, one of the cheapies from China that are all over eBay may have been the problem, of course, but the one I used is supposed to be ATA-33 compatible, and I have one like it that works just fine in a PowerBook Duo 2300c.
Ho hum. So last evening I installed an old 3GB conventional hard drive (Fujitsu) in the 2400c. As a result, the 2400c works perfectly again and wakes from sleep as it should. I took this step on arrival of a PCMCIA CF adapter that I had bought for a small sum, and I now have MacOS 8.6 installed both on the internal hard drive and on the CF card. The PCMCIA-CF combo works just as it should. Use of the latter as needed will, I hope, result in energy savings when using the main battery, and will allow me to swap files easily between the 2400c and a Pismo.
Subjectively, the PCMCIA CF drive in the 2400c seems a little slower than the conventional drives, but only a very little. Generally speaking, the machine seems satisfyingly snappy when running from CF.
This was quite an ordeal, as it is not a trivial matter to install, test and troubleshoot a hard drive something like 10 times repeatedly on a 2400c. They are quite a pain to service in this way, as the task requires very nearly complete disassembly, and there are a great many screws to contend with. This problem was accentuated by having needed earlier to disassemble the machine in order to install a new backup battery, a process which I have reported on in another thread — the cells needed are easily acquired, easily soldered, and are cheap.
However, following my pains I have success, in that I finally have my 2400c, which I rescued from a 'dead' state, in tip-top working condition.
