[Gaurav Mishra]

Any Via based Motherboards(mine is Km400-M2), Having these multi-channel disk controller that has special BIOS and drivers to assist the OS in performing software RAID functions. these are not actual raid Controller , But Emulate , It.

  I can`t get the motherboard changed , Please Help me on Installing Ubuntu Dapper on it

Hi Mishra,

isn't it the same bug as 22107 ?

[Gaurav Mishra (gauravtechie)]

No here is the case is different ,I don`t have SATA hard disk , And even have one hard disk only. so installer was supposed to recognize the Hard disk and Install Ubuntu. While going throgh manuals i found this is not real Raid Controller , While BIOS driver emulating like one. And these are Widespreading in India at a Alarming rate. So It`s a real problem

Can't you force the Bios not to have raid activated on the disk controller ?

Your problem is quite similar to bug 22107 in the way that Ubuntu does not provide software raid controller for installation.

Unless you want to dual boot with windows, the easiest thing to do is destroy the raid configuration in the bios utility, and install ubuntu on to the two seperate disks, setting up a pure software raid. Otherwise in dapper you should be able to get it working by installing the dmraid package. See https://help.ubuntu.com/community/FakeRaidHowto for more information.
