Speeding up OBSD bootup
Is it possible to specify the kernel that the hardware for which there are drivers probing for but I don't have in my PC is absent? Since OBSD has no suspend to disk/RAM, the bootup speed is critical when working with a laptop in public transport. Or are there any other possible ways how to speed up the bootup process? CL

There is also an entry in the FAQ: http://openbsd.org/faq/faq5.html#config Eric.

CL OpenBSD can suspend, man 8 apm apm -s for standby or apm -z for suspend state. I don't know if it will work with your device, but it does work on some -- Mark Mathias

Since OBSD has no suspend to disk/RAM, the bootup speed is critical when working with a laptop in public transport. You can use config(8) to disable drivers without building a new kernel, but you really have to know what you're doing. There's a tool called dmassage in the ports tree (sysutils/dmassage) which can help determining unused devices by looking at dmesgs's output. My experience (I tried it once on a Soekris Net4801) is that doing this kind of tuning won't gain you much speed at but time but is a real PITA if you want to plug some new device and have to re-enable it first to use it. Ciao, Kili -- Automake and autoconf deserve to wither and die, but unfortunately noone at GNU seems to make much of an effort to euthanasize them. -- Han-Wen Nienhuys, on Lilypond-devel mailing list

You might want to checkout ports/sysutils/dmassage/. Obviously, under improper use this might disable all hotpluggable USB stuff. C.

You might want to checkout ports/sysutils/dmassage/. Obviously, under improper use this might disable all hotpluggable USB stuff. Ideally, you should plug in all USB gadgets you ever plan to use with the laptop before running dmassage. If you can't do that, then you should specifically re-enable them. Be sure to enable things like the SCSI subsystem if you plan to use a USB mass storage device (pen drive, external hard drive, CD-/DVD-ROM, floppy drive). I made the mistake of leaving this out once after compiling a custom kernel, then weeks later plugged in a pen drive and wondered why I wasn't able to mount the damn thing. (Note this is exactly why you shouldn't compile a custom kernel unless you know what you're doing.) -- Shawn K. Quinn [EMAIL PROTECTED]
