How much ram do you have installed? A number of BIOSes have very very serious bugs in their MTRR setup on intel chipsets lately, and if you have more than 3GB of ram, some memory may not be configured as cacheable, and since linux likes to use ram from the top down you end up with the kernel in uncacheable ram and hence very slow booting. For many boards there are updated bioses to fix this mistake, but if there isn't yet you can tell the kernel at the boot command line that you have less ram than you actually have which will make it go much faster (since the small bit of uncached ram will not be used). Since you have 4GB of ram this is quite likely your problem. So check that you have the very latest BIOS version. You can test for the problem by adding 'mem=3072M' or 2048M or whatever, and see if it boots faster. If it does you can then grab the /proc/mtrr output as well as the dmesg output and post that to have someone check if the bios is making a mistake. A search on some forums seems to indicate that intel's 1705 bios does not fix it, and that people are going back to version 1669 to get a bios that does the right thing (who knows what it may break though). There is a 1707 that I haven't found any info on yet, so maybe there is a small chance it fixes the problem. Most other board makers have fixed this error by now (Asus and Gigabyte certainly have), while the kernel developers have had no luck what so ever convincing intel that they screwed up big time. There are attemps being made to make future kernels automatically disable any uncached ram if such a case occours again. AS for the DVD others seem to have pointed out that it uses an unsupported controller that needs the newer kernel so you can't help that with etch at all. -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
