If I boot with the console connected everything works fine. Did I miss something or mess up somewhere? Here's what I did to enable the serial console: Added to /etc/grub.conf: kernel /boot/vmlinuz-2.4.7-10 ro root=/dev/hda1 console=ttyS1,115200n8 Added to /etc/inittab: S1:12345:respawn:/sbin/agetty ttyS1 115200 vt100 Here's what a normal boot looks from the serial console: --------------------------------------------- Linux version 2.4.7-10 (bhcompile@stripples.devel.redhat.com) (gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)) #1 Thu Sep 6 17:21:28 1BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000004000000 (usable) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) On node 0 totalpages: 16384 zone(0): 4096 pages. zone(1): 12288 pages. zone(2): 0 pages.
