problems installin ubuntu 7.04 on hardware raid
First off, im a complete newbie, this is my first attempted linux install, so please excuse my ignorance.
The problem i am having is i cant create a partition to install to on any of my raid arrays. When the installer (ubuntu 7.04) gets to the "prepare disk space" screen i choose guided use entire disk /dev/i20/hda it goes through a few screens then generates "the creation of swap space in partition #5 of /dev/i2o/hda failed. Doing it manually in the menu doesnt work. using the text based installer generates the same error in a different wording. Using gparted when i try to set the disk label it gives an error: "error while setting disklabel" using parted from the command line:
ubuntu@ubuntu:~$ sudo bash
Warning: Unable to open /dev/hda read-write (Read-only file system). /dev/hda
has been opened read-only.
GNU Parted 1.7.1
Welcome to GNU Parted! Type 'help' to view a list of commands.
New disk label type? msdos
Error: Can't write to /dev/hda, because it is opened read-only.
*** stack smashing detected ***: <unknown> terminated

All the utilities see the correct sizes of the 3 arrays.
The controller is a promise supertrak 100 bios 1.00 build 13 (intel i960 chip). In its bios i set it to mode:Linux and deleted the previous arrays (and nuked windows) and defined new ones on two of the arrays, so they are unpartioned. (the other array is an ntfs partion which my data is backed up on.
Disabling acpi in the system bios.
Turning off pnp os installed in the bios, and disabling a serial and a parallel port and the on board usb, removing the sound card. Shuffled the pci cards to diffrent slots. (this got the installer to see my network card and detect that there were arrays on the card at least)
Disabled apic live=no-apic noapic nolapic at the boot menu of the cd.
i tried searching google and the install guide while i found plenty about installing on fake raid, i didnt see much about hardware raid from the last 5 years, prolly i dont know what to search for.
Doesnt look like a irq problem

Installing on a non raided drive off on the onboard ide works, but thats kind of not the point.
Any suggestions would be appriciated.
