Well, I did try LBA as well, but couldn't boot at all. boot2 did let me look at the root directory, but any further investigation (like trying 0:da(0,a)/boot/? ) produced junk and/or killed boot2. The Windows partition also didn't boot. Btw. according to http://www.pcguide.com/ref/hdd/bios/modesECHS-c.html the CHS parameters *are* within limits of the IDE/ATA standard; the "Large" mode is off limits since it can't get the Cylinder cound below 1024 without exceeding the max Heads. *sigh* what a mess :-) /step -- stephan mantler reality is in fact virtual.

Sectors more than 63 are not allowed for IDE drives at all.
What happens when you use the LBA geometry? Does the drive
not boot properly after being installed?

-current install on large disk in non-LBA mode
tonight i tried once again to install from 5.0-DP1 and the
2002-10-25 snapshot media. it has been interesting.
the disk i'm trying to install to is a seagate ST360021A
60G disk with a 30G windows partition already installed.
the BIOS accepts it either as a 28733/16/255 Cyl/Hd/Sec CHS,
1915/240/255 "Large", or 7297/255/63 LBA disk (yes, both
CHS and Large with 255 sectors).
I had the BIOS set to "auto" during the initial install, which
apparently defaulted to CHS mode. Windows is happy to work in
both CHS and Large modes, so i subsequently tried both
settings for the FreeBSD install.
However, sysinstall (neither from the 4.7-mini ISO nor the
5.0 snapshots i have) refuses to accept either and
insists on the LBA geometry. using to manually set the
geometry doesn't help ("you have entered an invalid geometry,
a more likely blah blah"). Wizard Mode let me enter the BIOS
geometry but apparently refused to write anything back to disk.
My next try was to create the partitions (er, slices) in Windows
and try to go from there, but that didn't work out either. Disklabel
just wouldn't cooperate.
For the time being I'll wipe out another disk and install there,
but i sure wonder which detail i've missed.
regards,
-stephan
