Sorry, 0x07 is overkilling solution. I tested all combinations now. 0x00 Hangup 0x01 OK 0x02 Hangup 0x03 OK 0x04 Hangup 0x05 OK 0x06 Hangup 0x07 OK This result implys i586_bcopy is the source of this problem. Hmm... I'm not familiar with NPX instruction, but I think i586_bcopy or something depends on the NPX's initialization by BIOS. -- HOSOKAWA, Tatsumi E-mail: hosokawa@mt.cs.keio.ac.jp WWW homepage: http://www.mt.cs.keio.ac.jp/person/hosokawa.html Department of Computer Science, Keio University, Yokohama, Japan
