Unfortunately, it seems there is no such setting in BIOS menu to disabling DMA. I did patch to stop looping and got the message: http://www.imasy.or.jp/~ume/FreeBSD/CF-R4/cf-r4-btx-halted.jpg I heared from takawata-san that EIP=0x107 indicates runaway. I could install FreeBSD by PXE boot from 6.0-CURRENT-SNAP004-i386-disc1.iso. It's fine to boot FreeBSD which is installed on HDD. It seems BTX-halted occurs when loading loader or kernel via legacy USB. I heared from Panasonic folks that they improved their legacy USB code for their latest series including CF-R4. It seems there is some issue in their improvement, and our BTX hits the weak point of their improvement. However, DOS, Windows and NetBSD are still bootable on CF-R4...
