NEW! - ide-cd.c now supports door locking and auto-loading.
- Also preliminary support for multisession
and direct reads of audio data.
+NEW! - the hdparm-2.6 package can be used to set PIO modes for some chipsets.
For work in progress, see the comments in ide.c, ide-cd.c, and triton.c.

more generally compatible method of achieving the same results (DOS access
to the entire disk). However, if you must use DiskManager, it now works
with Linux 1.3.x in most cases. Let me know if you still have trouble.
+
+My recommendations to anyone who asks about NEW systems are:
+
+ - buy a motherboard that uses the Intel Triton chipset -- very common.
+ - use IDE for the first two drives, placing them on separate interfaces.
+ - place the IDE cdrom drive as slave on either interface.
+ - if additional disks are to be connected, consider your needs:
+ - fileserver? Buy a SC200 SCSI adaptor for the next few drives.
+ - personal system? Use IDE for the next two drives.
+ - still not enough? Keep adding SC200 SCSI cards as needed.
+
+Most manufacturers make both IDE and SCSI-2 versions of each of their drives.
+The IDE ones are usually faster and cheaper, due to the higher data transfer
+speed of PIO mode4 (ATA2), 16.6MBytes/sec versus 10Mbytes/sec for SCSI-2.
+
+In particular, I recommend Quantum FireBalls as cheap and exceptionally fast.
+The new WD1.6GB models are also cheap screamers.
+
+For really high end systems, go for fast/wide 7200rpm SCSI. But it'll cost ya!
