If anyone here plays Nethack, the newere kernels use utf_8 by default, which is going to screw up Nethack.

You will need to disable the utf_8 with an append in lilo.conf to get the old behavior.

Just a thought, since I spent the last 1.5 weeks wrestling with it.

Config settings for hdc vs sr0
What settings are chosen when configuring custom kernel (during make menuconfig or make xconfig) so that sata cd/dvd shows up as /dev/hdc instead of /dev/sr0?

When using generic-smp kernel, dvd is hdc.
When using what should be reasonable choices it shows up as sr0.

I recently build 2.6.25.11 and tried to copy as much from generic-smp config file, but with built in file systems and dvd showed up as hdc. I'll review config files and post what appear to be differences in near future, but from memory I didn't think the settings made sense for the result.

Below is the options I chose in make xconfig to get sata dvd show up as /dev/hdc on gigabyte GA-MA78GM-S2H. Also shown is which settings were different in the kernel that has the dvd at /dev/sr0.

Only big difference I can see is the ATI IXP under ATA. I think this might make sense if the SATA dvd is in ide mode in bios. Would any of the other differences cause this effect?

Code:
Bus options
 - pci express off
-Support for pci hotplug
--ACPI and SHPC as M
Device Drivers
-ATA
--Enhanced IDE... Y
---Include ATA/IDE-2 Disk  Y
---Include IDE  CDROM      M
---Include ACPI support Y, (/dev/sr0 version has this off)
---legacy proc/ide   Y
---generic/default chipset  Y, (/dev/sr0 version has this off)
---Probe ide in bus order Y, (/dev/sr0 version has this off)
---Generic PCI IDE chipset support  Y, (/dev/sr0 version has this off)
---RZ1000 fix  Y, (/dev/sr0 version has this off)
---AMD NVIDIA  Y
---ATI IXP   Y, (/dev/sr0 version has this off)
---JMicron Y
---Intel PIIXn  Y
-SCSI
--RAID   M, (/dev/sr0 version has this off)
--SCSI Disk support Y
--SCSI CDROM   M
--SCSI generic  M
-SATA
--AHCI  Y
--Intel ESB, ICH... Y
--NVIDIA   Y
--ACPI Firmware  Y (/dev/sr0 version has this off)
--AMD/NVIDIA  Y
--ATI PATA   Y
--JMicron PATA
-i2c
---I2C Device Interface M
--I2C algorythms
---M for both
--I2C hardware
---Intel PIIX4  M

RESULT SATA DVD shows up as /dev/hdc

lsmod gives: (less snd and usb stuff)

Hello,

Im just starting to build my first kernel, and Ive downloaded the latest stable version, uncompressed it, and moved into the folder.

basically what I want to do, is simply use the running kernel .config (2.6.24.5smp), to build the latest source (2.6.25.13).

looking at a guide http://wiki.droplinegnome.org/index....Slackware_12.0, I issued this command

Code:
zcat /proc/config.gz > .config
to copy the current kernels .config into the source dir of the new kernel.

however, when i run 'make oldconfig', I get these errors:

I thought that this would simply build a new kernel with the old kernels options and there wouldnt be a problem.

could anyone tell me where Im going wrong on this?

They're not errors, but new options that have been added to the kernel since 2.6.24. You will have to answer each with yes, no, or module.

Cheers, Leon.

My config is called .configmy How can i be sure make oldconfig will pick it up? I did this by make menuconfig- then saving alternate and then copying alternate over .config (default). Then i do make. I know this is not correct.

I would like to post in response only to encourage those who want to make a good kernel to go online and find a spec sheet for their chipset. I found one for mine (I own laptops: one is an Intel ICH4, one is an Intel ICH7) and that helped me trim out of the kernel that which I do not have, and also to add things that I do have.

As for kernel size, the majority of it seems to be caused by a generic CPU choice and then Generic X86 optimizations. I would encourage those who are to build a kernel to pick their actual CPU, disable Generic X86 optimizations, and to disable SMP/SMT if they do not have a dual processor/core machine. This alone, along with Optimize for Size, seems to cut the kernel image and most module sizes almost in half.

The Generic and Huge kernel builds in Slackware are excellent at what they do (i.e. in booting almost any machine), but they are not specific to any machine. While I would encourage their use as a starting point for optimizing, and also as a FailSafe type image for emergency use, it is easy to make a much faster, more trim kernel for your machine simply by making a few minor tweaks.

Slackware rocks!

Hi,
I wrote a Linux 2.6 kernel compile guide of my own a while back - perhaps some of the people reading this thread would like to read it :-)

problem with generate-modprobe...and more.....
Hi to all,i want to use ext4 on my slack machine, and i must use kernel 2.6.29.1 . So i tried to install to my machine but....kernel panic appeared ,again.....gggrrrrr.

Explain: i follow the guide , which is in the first page but when i tried to use generate-modoprobe
command not found

Nevertheless,when my machine boot to new kernel an error occurred which has to do with file system.

My partitions is:
Quote:
cfdisk (util-linux-ng 2.14.1)

Disk Drive: /dev/hda
Size: 80026361856 bytes, 80.0 GB
Heads: 16 Sectors per Track: 63 Cylinders: 155061

Name Flags Part Type FS Type [Label] Size (MB)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
hda1 Boot Primary NTFS [^D] 40895.52 *
hda2 Primary Linux swap 509.97 *
hda3 Primary Linux ext3 18622.30 *
hda4 Primary Linux ext3 19995.98 *
Unusable 2.62 *
From dmesg i show that tries to mount wrong fs type, something like romfs

Does anyone have an idea????
