Doesn't FreeBSD require a 1.44MB disk to install from? That would give us 18spt, or 9216 bytes. That should give enough room for bad144 as well as the recent enhancements. Unless there are some harddisks that have less than 18spt. Looking through /etc/disktab, I see: pan60|Panasonic Laptop's 60MB IDE:\ :dt=ST506:ty=winchester:se#512:nt#13:ns#17:nc#565:\ ^^ So maybe 17 should be the upper limit. That would make life harder on those people who need to boot from 1.2MB disks, but they are not going to be installing from any recent install floppy anyway. That may require yet another directory in /usr/src/sys/i386/boot for 1.2Meg disks though... Maybe what we need is a bootblock configuration file similar to what the kernel uses :-) -- Zach Heilig -- zach@gaffaneys.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe hackers" in the body of the message
