If so, did you need to do anything special? I cannot get my retail DVD of 10.0 to load onto a machine with an Adaptec 2100S RAID Controller. I know the hardware is OK. 9.3 loads without a problem. 10.0 sees the controller and the arrays during the install, and everything works all the way up until the first reboot. Then the system hangs right after: System Boot Control: Running /etc/init.d/boot.local done If I CTRL+ALT+F10 I get this: pci_hotplug: PCI Hot Plug Core version: 0.5 shpchp: acpi_shpchp:\_SB_.PCI0 evaluate _BBN fail=0x5 shpchp: acpi_shpchp:get_device PCI ROOT HID fail=0x5 I2O subsystem v1.288 i2o: max drivers=8 i2o: checking for PCI I20 controllers...

I've tried disabling ACPI. It still locks up. I've tried taking one of the CPUs out so that the SMP kernel isn't installed by default. No difference. 10.0 load correctly if I use the onboard IDE controllers. I just can't get it to install when using the 2100S. Thanks in advance. Ken
