I've been trying to restore a BackupEdge full backup of an SCO 5.0.6 system
to an 80G SATA disk on an Intel S3000AHLX system board. This has not gone well.

Every time I boot the RE2 media the hard disk geometry comes back as
4 heads, 17 sectors, 4791 cylinders.

This is the output of defbootstr wd.debug=g:

wd_calc_geom(total_Blks = 15663014888x)
wd_calc_geom: head spin: sec = 63, heads = 16, spcyl = 1008, cyl = 155061
wd_calc_geom: head spin: sec = 63, heads = 32, spcyl = 2016, cyl = 77530
wd_calc_geom: head spin: sec = 63, heads = 64, spcyl = 4032, cyl = 38765
wd_calc_geom: head spin: sec = 63, heads = 128, spcyl = 8064, cyl = 9729
wd_calc_geom: head spin: sec = 63, heads = 255, spcyl = 16065, cyl = 9729
wd_calc_geom: returning sec = 63, heads = 255, spcyl = 16065, cyl = 155061
wd_set_geom: bootmisc.bioshds = 255, bootmisc.biossecs = 63, bootmisc.bioscyls = 9729
wd_set_geom: romTab hds = 4 romTab sec = 17 romTab Cyl = -536867492 Magic = 0x00
wd_set_geom: ValidTrans, heads = 4, sec = 17, cyl = 4791
wd_set_geom: final heads = 4, sec = 17, cyl = 4791

This makes fdisk unusable as fdisk only lists 19164 tracks (approximately
166M Byte).

I forced a restore by using UBC4Win boot CD and partition magic and defined
a UNIX partition that came out to be partition #4 as displayed by fdisk
that is about 40G. Running divvy -i and adjusting the divisions resulted
in a 4G root and 6G /dev/u file system and I was able to restore the
backup edge archive to the disk.

defbootstr with biosgeom=(9729,255,63) results with the 4hd, 17 sec, 4791
cyl disk paramaters.

dparam -w /dev/rhd00 `dparam /dev/rhd00` does no good, still 4,17,4791
dparam -w /dev/rhd00 9219 255 0 0 0 0 0 63 does not help, still 4,17,4791.

Is there any secret switch to wd.debug=g that over rides the
wd_set_geom: romTab hds = 4 romTab sec = 17 romTab Cyl = -536867492 Magic = 0x00
wd_set_geom: ValidTrans, heads = 4, sec = 17, cyl = 4791
wd_set_geom: final heads = 4, sec = 17, cyl = 4791

"ValidTrans" that results in the wd_set_geom: final heads = 4, sec = 17,
cyl = 4791?

Attempting a fresh install from 5.0.6 media with wd506 bootload driver
was no better. Still had the problem with 4,17,4791 disk parameters.

corrected typo:

I plan to try that today as well as a different SATA hard disk
and replacing the PATA DVD with SATA DVD.

I burned yesterday trying to get Backup Edge (from the restored
image) to backup the system with no luck. Backup Edge always
comes back with "no media detected" in the LG DVD PATA drive.

The Intel S3000AHLX is listed as certified with SCO 6.0 and
5.0.7. with a note that 5.0.7 will install with "wd BLTD Verison 3.0
(osr507)" floppy.

The S3000AHLX is a decommissioned Windows Server 2003 system and
was thought to be suitable for migrating the 5.0.6 system from
the 400MHz PII that has been running for over 12 years.

Go thee unto the CMOS settings and change the SATA mode from AHCI to
IDE emulation. Be sure to power down the computah and drive (pull the
plug) after making the change.
