Good to hear it's working! Perhaps if there was a mismatch between boot1/boot2 or something. I'm not expert on the internals so I might leave this one there.

RE: Boot loop in FreeBSD 5.2-RELEASE after install - FIXED!
Well THAT'S weird... I wondered if there might be some strange data left on the drive (I had a 4.7-RELEASE install on it prior to this), so I stopped the system in POST and entered the Adaptec system utilities. I then did a low-level format of the drive. Reinstalled and Hey Presto - booted up fine! I wonder if the /boot/loader program found some bad data left over from a prior install that it didn't validate and that corrupted the boot process? Dunno, but it's up now. THANKS!!

This one didn't succeed either... Sigh... It's clear I'm getting to the /boot/loader program and it's running; it just keeps looping with no indication of an error (until it runs out of heap, which is the assertion failure). Do you know if there's a method of bypassing the loader program and directly booting the kernel? I tried stopping the second stage boot and booting "/boot/kernel/kernel". The boot program spins for a (long) while loading it, but I'm guessing something's missing 'cause once it transfers control to the kernel the system freezes. tfrank> Have you tried 4.9-RELEASE on this system? No, I have several other 5.2 systems (built from these same CDs) and I kind of wanted to minimize the number of variants. This IS the only dual-drive SCSI-only box I have going though... Maybe I should just slap an IDE drive into the box (there's space and even cabling available) and install to that??? tfrank> I understand that 5.2.1-RC2 ISO is also available which might be another option. I know - it came out the weekend after I downloaded and burned the 5.2 ISO. G :-) Thanks!

Looks like the loader is just looping until it runs out of > heap. That suggests that it may be confused somehow. I saw the crash/assert type scenario if the boot blocks are not installed properly. Ie the MBR is updated with the bootmgr (F1 .. bit) but the 2nd/3rd stages were corrupted somehow. (In my case I accidentally overwrote the blocks with some experiementation) You can reinstall boot blocks using bsdlabel (or disklabel on 4.9) If you can boot from floppy/CD, get into fixit mode. Then run: bsdlabel -B da0s1 (assuming da0 is the disk you are trying to boot from) > If I try to boot directly into the kernel the cursor changes from a > blinking underscore to a solid block and the system just locks up. > > In no case is there an error message or any other indication that > something is weird. Have you tried 4.9-RELEASE on this system? I understand that 5.2.1-RC2 ISO is also available which might be another option.

They don't work. Fortunately I was able to: 1. Hook a null modem to the serial port and my laptop. 2. Run hyperterm on my laptop to view serial port data. 3. During the initial boot load hit ESC to get the "Boot:" promt, then do "-h" to switch to serial console. 4. Capture the stuff on the serial console. What it does is repeatedly go through the BTX boot loader, saying something like (this is from memory): BTX loader... BIOS Drive A is disk 0 BIOS Drive C is disk 1 BIOS Drive D is disk 2 BTX loader... BIOS Drive A is disk 3 BIOS Drive C is disk 4 BIOS Drive D is disk 5 BTX loader... and so on. Eventually it runs out of drive numbers and starts saying "Can't figure out our boot device" a few times, then crashes with an assert error. Looks like the loader is just looping until it runs out of heap. If I try to boot directly into the kernel the cursor changes from a blinking underscore to a solid block and the system just locks up. In no case is there an error message or any other indication that something is weird. tfrank> Do you get past the "F1 FreeBSD" part to the loader? tfrank> ie do you see a "-" appear on screen? Yes.

While I cannot perhaps comment on your problem, you can try either pressing 'pause' key or 'scrolllock' which might help depending on where the problems are occuring. Do you get past the "F1 FreeBSD" part to the loader? ie do you see a "-" appear on screen? Can you perhaps try a serial console? If you can get into the boot loader you should be able to set com1 as your console.
