QNX install on vmware ESX3i
Now that VMware is giving away ESXi for free, I decided to try installing QNX on it.
First of all, VMware ESX(i) does not support IDE hard drives, only SCSI. But SCSI support is available for a QNX-
compatible Buslogic host adapter, so it should be ok.
There are two problems that I see that prevent this from working:
First, On both the 6.3.0SP3 and 6.3.2 installation CDs, in /etc/system/enum/devices/block, there are two lines for the
Mylex/Buslogic controllers, one of which is the correct one, but then the "requires" line loads the AMD driver instead
of Buslogic!!
And second, devb-btmm does not auto-detect the virtual Buslogic controller, even though it's a supported model. If you
manually specify the I/O port and IRQ, then it loads properly.
Note also that looking at our development system, once QNX is installed, /etc/system/enum/devices/block is correct, or
at least tries to load the BusLogic driver, unlike the one on the CD.
Here is the excerpt from /etc/system/enum/devices/block on the installation CD:
device(pci, $(PCI_VEND_MYLEX), 1040) # Buslogic
device(pci, $(PCI_VEND_MYLEX), 8130) # Buslogic
requires(devb-amd $(DEVB_OPTIONS), "amd pci=$(index)")
Note how it detects the Buslogic controller and then loads devb-amd!
Here is the output of the "pci" command showing the virtual controller:
Class = Mass Storage (SCSI)
Vendor ID = 104bh, BusLogic
Device ID = 1040h, BT-946C (BA80C30) [MultiMaster 10]
PCI index = 0h
PCI IO Address = 1060h enabled
PCI Mem Address = f4800000h enabled
PCI Expansion ROM = 0h disabled
PCI Int Pin = INT A
Interrupt line = 9
CPU Interrupt = 9h
Here are the outputs of devb-btmm with no options, showing how it does not auto-detect the controller (the pci=0 option
doesn't help), followed by forcing the ioport and irq where it loads successfully:
# devb-btmm
# xpt_configure: No btmm interfaces found
# devb-btmm btmm ioport=0x1060,irq=9
# Path=0 -
target=0 lun=0 Direct-Access(0) - VMware Virtual disk Rev: 1.0
Is there anything that can be done to "patch" the installation CD?
Thanks,
lew
