So it can be result from the missing device (bad USB connection or missing floppy drive). What our INT13 related code is currently missing, is the reset on error calls - to try to get the IO system back to stable state. Or to be exact - the reset is not always used. Actually, it's the same SATA cable/disk which works for UFS/ZFS. > rgds, > toomas > >> gptzfsboot: no zfs pools located, can't boot >> --- >> >> The disk is: >> --- >> 512 # sectorsize >> 2000397852160 # mediasize in bytes (1.8T) >> 3907027055 # mediasize in sectors >> 0 # stripesize >> 0 # stripeoffset >> 3876018 # Cylinders according to firmware. >> 16 # Heads according to firmware. >> 63 # Sectors according to firmware. >> WD-WMAUR0112162 # Disk ident. >> Not_Zoned # Zone Mode >> --- >> >> UEFI is not available at the motherboard. >> >>> Namely, what I have found is that in some systems the INT13 ah=08 can result with unexpected results - error from command reported or disk count not reported etc - something not really expected. It also may have to do about what other devices are there. And also if the system has plain BIOS or BIOS emulated on UEFI. >> -- WBR, bsamReceived on Mon Jul 10 2017 - 20:15:30 UTC
