Hi:

I just purchased the 4-CD kit from Walnut Creek and installed 4.1 from scratch on a Digital Celebris P133 box [Phoenix 4.14 BIOS]
with an Adaptec AIC 7850 SCSI controller and a 2GB Seagate Barracuda SCSI disk. The install goes fine [I have to boot from floppy as
this system doesn't support bootable CDROM].

However, after install, I cannot boot from the hard disk [which shows up as C: i.e. disk1].
I can boot from floppy and do 'set currdev=disk1s1a; unload; boot' OK but can't boot directly from the hard disk.

If I install 4.0 from scratch and then *upgrade* to 4.1 it boots OK. I have duplicated this on a 2nd Celebris P133 machine [same
CPU/BIOS, but 3 SCSI disks].

I understand that the 4.1 i386 bootstrap code is 2x bigger. Is there some magic that needs to happen for an older BIOS to work with
the new boot system? I tried 'boot0cfg -o packet' but got no improvement. The system fails to boot whether I use the boot manager or
the basic FreeBSD-only loader.

Thanks for any info you can provide - Jeff Stelzner
