Hi all, I was banging my head against the wall too long yesterday, so I have broken down, and have to ask. Any help on this matter is greatly appreciated.
Here is what I'm trying to do. I have two computers, both running 4.8, clean, minimal installs. They have two serial cables connected to each other to act as serial consoles, and -Dh has been added to /boot.config, along with ttys having been updated. The console bit works great. What I want to be able to do, is completely rebuild one of the machines remotely. So I log into one, serial over to the other, and reboot it. Then, when the loader comes up, I stop it, and break to the "ok" prompt. I unload the kernel that was starting to load, and at this point, want to boot off CD, to rebuild the system, as though I had gone into the BIOS, and set the CD as the first boot device. However, I don't have remote access to the BIOS, so I can't do this. Here is some information about the systems, and what I have tried so far: They are identical computers, that I built myself, very default machines. IDE everything. atapci0: <SiS 5591 ATA100 controller> port 0xff00-0xff0f at device 2.5 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ata1-slave: ATAPI identify retries exceeded ad0: 38166MB <ST340016A> [77545/16/63] at ata0-master UDMA100 acd0: CDROM <FX54++W> at ata1-master PIO4 I have tried all combinations of load that I can think of. And I have tried setting loaddev and root_disk_unit to all sorts of things. Here is the output from a lsdev: cd @ 0xff5c disk @ 0xef68 disk0: BIOS drive A: disk1: BIOS drive C: disk1s1a: FFS disk1s1b: swap disk1s1e: FFS disk1s1f: FFS disk1s1g: FFS pxe @ 0xd6d8 I have also tried just doing an ls on the device, by setting currdev to all sorts of things...like cd9660:cd, just 'cd' and the BIOS physical addresses in the form X:acd(Y,Z) [0-4]:acd([0-4],[a-c]) No joy. I have also tried booting with the -C option, and here is the tail end of that attempt: acd0: CDROM <FX54++W> at ata1-master PIO4 Mounting root from cd9660:cd0a no such device 'cd' setrootbyname failed iso_mountroot: can't find rootvp Root mount failed: 6 Mounting root from cd9660:acd0a cd9660: RockRidge Extension init: not found in path /sbin/init:/sbin/oinit:/sbin/init.bak:/stand/sysinstall panic: no init No joy. I'm trying to think what other information might be useful. As I see it, the problem is, that once a version of FreeBSD has been installed, and the loader loads off the HD, it doesn't want to have anything to do with the CD any more... I realize I have other options, like PXE or FTP, or having an "install partition", to hold an install of BSD, just to install to the other partition. I really don't want to go down these roads right now, since I want to be able to have someone pop in a new CD, to switch around versions of BSD running on these boxes. Help anyone!?
