Any better luck after enabling "LBA access" in boot1 as a build option (added back a few weeks ago), or does the BIOS not support this? BTW: Is this a genuine hard drive, or some form of disk-on-a-chip? I seem to recall the BIOS geometry in some cases uses a small number of sectors per track, which may push part of the 'a' partition beyond the 1023 CHS limit. Anyway, if some debugging code would help here, let me know. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
