Can somebody point me at something which describes:
Device using Wide/Sync transfers at 11.4 MByte/sec, offset 15
Transinfo settings: current(43/15/1), goal(43/127/1), user(43/127/1)
[ I've worked out that the "/1" means "wide" (0 for narrow),
but I don't know what the meanings of `offset' and `period' are.
Ultra Enable Flags: 0x0000
is also a concern, as the 7896 and SEAGATE ST118202LC are LVD
It seems that "period" is 250/Mbit of the bus speed,
but what is offset (0, 8 or 15) ? Most Wide are 8, but not this one.
As "SEEPROM found and used", I guess I need to tweak the SCSI BIOS - yes ?
