Hello,

I am trying to install gentoo on a new system:
Quote:

Intel DG965RYCK, G965, LGA775, PCI Express, 4x DDR2, ATX
Intel Core 2 Duo E6300, 1.86Ghz, 1066Mhz, 2MB, LGA775
Memory 1024MB DDR2 PC2-5300, 667Mhz (2x 512)
SATA-II Western Digital 160Go, 8Mo, 7200RPM


I am using the live CD 2006.1 .
After choosing the boot option the system started loading few modules and than it shows me:
Quote:

Loading gentoo........................
....
...
>> activating mdev
>> Making tmpfs for /newroot
>> No bootable meduim found. Waiting for new devices
!! could not find CD to boot, something else needed

>> Loading keymaps...
>> Determining root device.
The root block device is unspecified or not detected.
Please specifu a device to boot or "Shell" for a shell.


I tried using CD gentoo 2006.0 and 2005.1 but I got black screen after choosing the boot option...

Do you know how to fix this problem.

Thank you
Dany

Intel Core Duo systems often have the JMicron IDE/SATA controller as well as the Intel ICH8 SATA controllers.

The LiveCD doesn't have a kernel that supports these, support seems to have arrived in the 2.6.19 kernels.

You might like to have a look at these threads, in particular the first and second which offer a version of the Gentoo LiveCD with a kernel which supports these controllers

Experimental & final release (GentooCD with JMicron-supp.)

amd64-release of "small gentoo", liveCD with JMicron-support

Intel Core 2 system woes (JMicron, JMB363 and other...)

Roundup: Kernel with JMicron support (JMB363, 361, 360, 36x)

New Dual Core build

Another thread says that if you want to have a 32-bit system you should use the x86 LiveCD and if you want to have a 64-bit system then you should use the AMD64 LiveCD (yes, AMD64)

In fact, you should really look at Prepping for a new install as it contains a lot of useful advice.

I have installed the 2.6.19 and enabled the controller but still no CDROM however I do Have this :
Code:
02:00.0 IDE interface: Marvell Technology Group Ltd. Unknown device 6101 (rev b1) (prog-if 8f [Master SecP SecO PriP PriO])
        Subsystem: Marvell Technology Group Ltd. Unknown device 6101
        Flags: bus master, fast devsel, latency 0, IRQ 10
        I/O ports at 1018 [size=8]
        I/O ports at 1024 [size=4]
        I/O ports at 1010 [size=8]
        I/O ports at 1020 [size=4]
        I/O ports at 1000 [size=16]
        Memory at 50100000 (32-bit, non-prefetchable) [size=512]
        Capabilities: [48] Power Management version 2
        Capabilities: [50] Message Signalled Interrupts: 64bit- Queue=0/0 Enable-
        Capabilities: [e0] Express Legacy Endpoint IRQ 0


which I think is the PATA controller, I have enabled every marvell option in the kernel but still no go, any ideas?

The latest pci.ids (which you can download using /usr/sbin/update-pciids) has
Code:
11ab  Marvell Technology Group Ltd.
# Found on Intel DG965WH Desktop Board
        6101  88SE6101 single-port PATA133 interface
but, as you've already found out, there is no drivers/ata/pata_xxx.c for Marvell and nothing under linux-2.6.19-gentoo-r4/drivers/ide either.

As the chipset is described as 11ab/6101 (a first level entry) it looks as though it's a real Marvell chipset otherwise it would be a second level entry.

There is a mention in http://kerneltrap.org/comment/reply/7020/208330 "build a new kernel 2.6.19.2 with Marvell 88SE6101 patch" and there is also http://lkml.org/lkml/2006/10/16/157 with the actual patch (for linux-2.6.19-rc1-mm1), it might be worth looking at the mm-sources.

Searching sys-kernel/mm-sources-2.6.20_rc6-r1
Code:
# cd drivers
# find -name \*.c|xargs grep 88SE6101
# find -name \*.c|xargs grep 6101
./ata/pata_marvell.c:   if (pdev->device == 0x6101)
./ata/pata_marvell.c:   { PCI_DEVICE(0x11AB, 0x6101), },
so it looks as if that's your best bet.

[Edit] In all that, I'd forgotten about booting: if you can't boot a CD to install, it's not much use knowing that there is a kernel which might solve your problems.

However, you might like to have a look at the threads Experimental & final release (GentooCD with JMicron-supp.) and amd64-release of "small gentoo", liveCD with JMicron-support. kernelOfTruth has created versions of the LiveCD with a new kernel — he may be willing to make (or may already have made) a LiveCD with the above mm-sources kernel on it so you can boot.

It's worth joining a thread (the first if you are going to run a 32-bit system, the second for a 64-bit one) and asking, don't you think?

I downloaded a version from this site http://www.kernel-of-truth.net/downloads_kOT.html and now I am on my way to install gentoo on the new system and it's working fine...

Thank you

2.6.20 works great out of the box :-)
