>Description:
Hi,

I am trying to netboot 7.1 amd64 on bare metal systems (HP blade class) and within VMware ESXi. In both scenarios I use PXE to boot memdisk from the Syslinux project which then loads a FreeBSD harddisk image. This disk image contains the BTX loader (as created by "bsdlabel -w -B") and the /boot directory from the 7.1-RELEASE-bootonly.iso. Booting this fails with various errors. Either the BTX halts and dumps CPU registers until the machine is reset, or BTX stops after loading text segment and powers off the machine after a while.
Booting 7.0-RELEASE amd64 this way works fine, as 7.1-RELEASE i386 and 7.0-RELEASE i386 does. CD boot works fine for all 4 releases.
Don't hesitate to contact me by mail if you need further info, dumps, etc.

Regards
Felix
