Hello, Somebody on the list give me an advice to switch (in the BIOS) IDE emulation from "Legacy IDE" to "Native" I noticed that when I select "Legacy IDE" the access turns to UDMA 100 with no other choice. When I try it I get a kernel panic at boot ... not syncing ... please append a correct "root=". So it is a misfit between the drivers and the system or with the way the SATA drivers works. Are the SATA hd devices always called HDx with the SATA driver working or are they called SDx like the Scsi hd ? On one of my home systems I lost an SCSI disk and replace it by a standard IDE one and the disk is seen as SDE after the SCSI disks (kernel 2.6.20). Knoppix is Debian based, so the system seems to be OK, and I update it with apt-get set to etch. I recompile the last 2.6.19 with SATA set to "Off" and the machine boots (Legacy IDE) with the same bad disk performance. A simple "vi" on a file is long as on the venerable Amiga which I used as reference. (Yes an Amiga 2000 works with Linux, this one has known its firts kernel before the 2.0 and runs with a Debian since 2.0.x, I think x was 10 to 12 many years ago, it runs now 2.6.18 with full success). On my "big" (2x AMD 2Ghz) system the same "hdparm -t /dev/sde1" gives 66.46 Mo/s on the IDE disk. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

I don't remember if they are in 2.6.20 or will go in 2.6.21. Usually having to set the bios to anything other than native SATA/enhanced/whatever they call the setting that does no emulation, is not a good sign of having the right working drivers. I think the debian kernel team has experimental 2.6.20 kernel packages that you could try to see if it is any better. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Problems booting from SATA in a HP DC5750 (ATI SB600 ?)
Dear Srs, I've just suceeded performing the base install from an etch snapshot CD1, in a HP DC5750, which uses an ATI SB600 to provide SATA. I had to choose "Native IDE" in the bios settings do install properly (other options are "Legacy IDE" and "SATA" - not the case, I have only one HD). The install went well - no glitch, and grub was put on MBR, as usual. However, during boot, the machine reports a lot of errors: * ata2: SATA Link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: Configured for UDMA/100 ata2: EH Complete ata2.00 exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata2.00 (irq_stat 0x4001) ata2.00 tag 0 cmd 0xa0 Emask 0x40 stat 0x51 err 0x20 (internal error) softresetting port * The pattern above is repeated 20 or so times, then boot proceeds and succeeds!!! Once up, the box runs ok, as far as I could evaluate. I've been googling around but could not find anything useful so far. Has anyone seen something like this? Any hints?

Not sure. I don't liek all in pnes personally, and I despise brother products (past experience with their laser printers was too painful, not to mention their idiotic fax machines). I am tempted to buy a xerox phaser 6120N since it is a nice colour laser, with good print quality, native postscript level 3, and ethernet connection for under $400. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Usually less than 2MB/s means you don't have DMA enabled, which usually means you are using the wrong ide driver or have a bad configuration somewhere.

There have been problems with some chipsets (mainly ATI, but also a few nvidia ones) where the system time would run at double speed.

The kernel headers package contains the configuration and header files matching your current kernel. The kernel source contains unconfigured sources (which include headers). The configuration part is rather important when building modules to match a kernel. And when building other things you only ever need the headers, since the source files are only used for building the kernel. Hence the need for kernel-headers package and no need for kernel sources. After all you don't need the sources to libc to compile a c program, just the standard c library header files. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I can in fact wait a bit for the gcc but the page you pointed out is interesting and I should have known. But I could not find the experimental build logs in there.
