This is the first time i have complied a new kernel .Previously i had installed from cd redhat6.2 .Compliled 2.4.0-test5 kernel and saw a different /var/log/dmesg . 1.Help me figuring what each of these lines say ? 2.Are there any command line html veiwers to traverse the documemtation ? 3.Are there any applications which help in browsing thru the source code ? Though there is too much to scroll, Any help in this regard would be acknowledged . ---------------------------------------------------------------------------- --------------------------------------------- Linux version 2.4.0-test5 (root@Pina) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 Thu Aug 10 18:31:19 IST 2000 BIOS-provided physical RAM map: e820: 000000000009fc00 @ 0000000000000000 (usable) e820: 0000000000000400 @ 000000000009fc00 (usable) e820: 0000000000010000 @ 00000000000f0000 (reserved) e820: 0000000000010000 @ 00000000ffff0000 (reserved) e820: 00000000016f0000 @ 0000000000100000 (usable) e820: 000000000000d000 @ 00000000017f3000 (ACPI data) e820: 0000000000003000 @ 00000000017f0000 (ACPI NVS) Scan SMP from c0000000 for 1024 bytes.
