You may want to >run it as chmod +rw /dev/ttyS? to give the permissions to user, group, >and other. chmod +rw has apparently zero effect here, I have to use numbers, as in chmod 0666 ttyS*, which does this: [root@coyote dev]# chmod 0666 ttyS* [root@coyote dev]# ls -l ttyS* crw-rw-rw- 1 root uucp 4, 64 Nov 10 10:45 ttyS0 crw-rw-rw- 1 root root 4, 65 Nov 10 10:45 ttyS1 crw-rw-rw- 1 root root 4, 66 Nov 10 10:45 ttyS2 crw-rw-rw- 1 root root 4, 67 Nov 10 10:45 ttyS3 [root@coyote dev]# setserial /dev/ttyS0 Cannot get serial info: Invalid argument [root@coyote dev]# setserial /dev/ttyS1 /dev/ttyS1: No such device or address [root@coyote dev]# I have rebuilt the 2.6.19-rc5 kernel I was using for FC2, to include the LVM stuff but haven't rebooted to test. Just copied into boot and used it fails because I wasn't using LVM with FC2. However, this is as good a time as any to save this in drafts and try that, brb in about 10 minutes after I test this. And it failed, I think I forgot to insert the udev pieces, the final msg before it self-rebooted was something about no such file: /dev/console. Humm, a make xconfig doesn't show a udev option anyplace. This is a kernel org kernel I'm building, and it runs great on the other hard drive. This would be easier if I could setup grub.conf to chain to the other drive, is this possible? If so how, because that would stop me from having to physically swap drives to revert to FC2. If I can chain to the grub.conf on hdb1, and edit that drives /etc/fstab to reflect its drive b, I should be able to just reboot to the other drive, and FC2. I have a manpage for grub, but it doesn't mention the chain command, and there is not a manpage for grub.conf or menu.lst in this install, so I'm blind & cannot RTFM in this case. [...] One other beef: With all the rebooting I just did to write the failure msgs down, I'm half blind from the consoles incessant flashing anytime somethings written to it. It doesn't do that when booting FC2, with any of my self-built kernels. Its very, like a random strobe light in your eyes, distracting. -- Cheers, Gene
