 |
|
A couple of questions from a rank newbie, all relating to kernel configuration.
I've just installed gentoo 1.4 on my ECS Desknote computer, and it's working very nicely, thank you.
But I want to have support for CD burning.
I have an IDE combo CDRW-DVD on the machine. So I want to enable SCSI emulation in order to do CD burning. When I installed gentoo, I just used the stock (gentoo-sources) kernel.
So
Q1 : My (stock) kernel has SCSI emulation as a module. But it also has IDE support for the CD installed (CONFIG_BLK_DEV_IDECD=yes).
Do I have to recompile the kernel, with IDE support for the CD either removed or modularized? Or can I leave it as is, and just install the SCSI emulation module (and add the ide=scsi bit to my grub menu)?
Q2: With my already-installed system, can I use genkernel --config to recompile the kernel?
Q3 : My computer has a Pentium 4 processor. If I recompile, should I add (or add as module) the "mpentium4" support instead of "m386"? Or in addition to "m386"? Will this affect any of the packages that I have already emerged?
Q4 : Gentoo does not mount my /boot partition when I log on. Once I've recompiled, how do I get the new kernel image in the /boot directory? Do I just mount the partition?
Sorry about all the low-level questions. |

You should be able to get CD burning working by just adding the hdx=ide-scsi boot option and loading the SCSI module. I don't have very much luck with modules, so my personal choice is to compile it directly in, but YMMV.

I don't use genkernel so I can't answer this one.

For starters I don't think you can compile this option as a module. I also don't think you can have more than one architecture selected. The 386 is the base x86 architecture; if you're not using a really old processor, you should select something higher (in your case the Pentium 4 option). It also shouldn't affect any of your already installed packages, and any new packages should be able to take advantage of it.

Yup, just go ahead and mount /boot when you're ready to copy over the new kernel. One of the reasons for not having /boot automount is so a rogue program can't overwrite your kernel and other boot related data.
Those weren't too low-level questions, I hope I answered the ones that I could sufficiently.
