hi everybody!! I'm very sorry but reading the post of Lor3nzo and trying what he wrote I have unfortunately discovered that my motherboard is not a "939Dual-Sata2" but a "939Dual-Vsata"...I'm very sorry for this mistake! However I tried to update the bios, from the version 1.20 to the latest 1.30 but nothing has changed.
sorry a lot for the mistake (that I'm going to correct in the first post) ** Description changed: I'm trying to install kubuntu feisty beta (i tried both the desktop and alternate i386) but the installer, and i think the kernel too, can't find my sata disk (i tried to "fdisk /dev/sda" but it replied "unable to open /dev/sda) - my motherboard is an "asrock 939-Dual sata II" + my motherboard is an "asrock 939dual-vsata" this is the output of lspci (i hope will help to find the problem) 00:00.0 Host bridge: ALi Corporation M1695 K8 Northbridge [PCI Express and HyperTransport] 00:01.0 PCI bridge: ALi Corporation PCI Express Root Port 00:02.0 PCI bridge: ALi Corporation PCI Express Root Port 00:03.0 PCI bridge: ALi Corporation PCI Express Root Port 00:04.0 Host bridge: ALi Corporation M1689 K8 Northbridge [Super K8 Single Chip] 00:05.0 PCI bridge: ALi Corporation AGP8X Controller 00:06.0 PCI bridge: ALi Corporation M5249 HTT to PCI Bridge 00:07.0 ISA bridge: ALi Corporation M1563 HyperTransport South Bridge (rev 70) 00:07.1 Bridge: ALi Corporation M7101 Power Management Controller [PMU] 00:11.0 Ethernet controller: ALi Corporation ULi 1689,1573 integrated ethernet.
