recording boot up info?

[unclepauly]

hello,

is there any way to print to a text file (or something), all the boot up info when the kernel loads? the reason i ask is, i have 2.4.27 and 2.6.19.2 on my laptop. the 2.4.27 kernel works just fine (this is because it came with the Debian download), but the 2.6.19.2 version has a few problems, like sound, pcmcia card not working, other stuff etc (this is because i installed it from source myself and i obviously have made some config errors). i just want to compare the boot up info from the version that does work, with the version that has problems, and see if this gives me any idea of what is going on. i have tried watching it on screen but it goes too fast!

thanks.

Boot up one and run dmesg > textfile1. This will print start up info into a file called textfile. Do the same with the second one then diff.

another thing you might try is comparing the .config files: look in /boot
for something like "config-2.4.27" or "config-2.6.xx.y"

or you might try copying config-2.4.27 to yr 2.6 source directory as .config,
then do "make oldconfig"
