Yes, the Rocket 133SB (Rocket133SB) HPT302 chip is apparently
supported by the HPT366.c file.
Ah! My bad. It seems that all those options WERE configured in my
kernel and the Highpoint IS being recognised. But there is a problem:
HPT302: IDE controller at PCI slot 0000:00:02.0
PCI: Enabling device 0000:00:02.0 (0000 -> 0003)
PCI: No IRQ known for interrupt pin A of device 0000:00:02.0.
Probably buggy MP table.

I suspect this is because I've disabled the device in the machine's
BIOS, in the belief that Linux would issue it an IRQ & so on. When I
re-enable the controller in BIOS & boot from the LiveCD the drive
attached to the controller shows up & I am able to mount it:
HPT302: IDE controller at PCI slot 0000:00:02.0 HPT302: chipset

drive ide2 at 0x2000-0x2007,0x200a on irq 11
Unfortunately, if I leave the controller enabled in BIOS then the PC
will attempt to boot from it, and not from the built-in RAID array on
which the operating-system is installed... thus I get a "non-sytem disk
or disk error". The CD drive is on an internal EIDE controller which I
can boot from whether the Highpoint is enabled or not. The system
itself is a 5 year-old Compaq Proliant server which was never intended
to have an EIDE hard-drives alongside its SCSI array, so I seem to be
unable to tell it to boot from the array rather than the Highpoint.
I believe I may be able to install GRUB on the boot sector of the EIDE
drive & point that at the /boot partition on the RAID array, but I
thought I'd check in here first. Is there any way to get the kernel to
choose an IRQ for the HPT302? I thought this was what plug & play
operating systems were about. Can the kernel be invoked with an append
which will assign it the IRQ11 recognised by the LiveCD? I've tried
furtling with the interrupts of the various controllers, but it's not a
very intuitive interface on this machine - might I be able to change
the boot order this way?
Many thanks in advance for any advices,
Stroller.
