SUMMARY
LOGSHOW is a utility that displays information about disk adapters, disk drives, CD-ROM drives, and tape drives installed on the system. LOGSHOW resides in the C:\OS2\SUPPORT directory.



MORE INFORMATION
The general format of an error log entry displayed by LOGSHOW is as follows:   devnam cccc mm/dd/yy hh:mm:ss - meaning of code additional information The following are the standard error log entry displays: devnam 000a mm/dd/yy hh:mm:ss-Informational:Real ESDI inquiry data follows: 00 00 00 00 00 00 00 00 GENERIC ESDI DISK TYPEnn

Where      Is         --      --

devnam     Normally DEVINQ, which is the temporary device name used while the device is being configured

mm         The disk type code specified during setup of the PC

devnam ffff mm/dd/yy hh:mm:ss - Informational: configure physical disk AOK

Apparent Geometry: ggggg hhhhhhhhh iiiiii jjjj kkkk llll Actual Geometry: ggggg hhhhhhhhh iiiiii jjjj kkkk mmmmm Media BPB: ggggg nnn ppppp qqq rrrrr sssss tt uuuuu vvvvv wwwww xxxxxxxxx yyyyyyyyy Recommnd BPB: ggggg nnn ppppp qqq rrrrr sssss tt uuuuu vvvvv wwwww xxxxxxxxx yyyyyyyyy

Where      Is         -       --

devnam     The name of the physical disk drive that has just been configured

ggggg      Sector size in bytes

hhhhhhhhh  The number of sectors on the physical volume

iiiiii     The number of cylinders in the physical volume

jjjj       The number of data heads accessing the physical volume

kkkk       The number of sectors per track

llll       Flags, in hex, that show how the geometry data was generated:

0x8000     Apparent geometry was already set by the time that the TSD first gained control.

0x4000     Actual geometry was already set by the time that the TSD first gained control

0x2000     Actual geometry was set from the apparent geometry by the TSD because the actual geometry was null

0x1000     Apparent geometry was set from the ROM data (INT 13                        function 8) by the TSD

0x0800     Apparent geometry was set from the BPB in the primary partition boot record by the TSD

0x0400     Media BPB was initialized by the TSD

0x0200     Recommended BPB was initialized by the TSD

0x0100     Recommended BPB was set from the BPB in the primary partition boot record by the TSD

0x0080     Geometry set from ROM by BID

0x0040     Geometry set from internal disk characteristics table by BID

0x0020     Geometry set using values determined through auto- configuration by BID

0x0010     Geometry set using values from INT 41 or INT 46 by                        BID

0x0008     Apparent and actual geometry set by BID

mmmmm      The cylinder number from which write precompensation is to be used

nnn        The cluster size

ppppp      The number of reserved sectors

qqq        The number of FATs

rrrrr      The number of directory entries

sssss      The number of sectors in the partition, if less than 65,536 sectors

tt         The media descriptor, in hex

uuuuu      The number of sectors used by each FAT

vvvvv      The number of sectors per track

wwwww      The number of heads

xxxxxxxxx  The number of hidden sectors

yyyyyyyyy  The number of sectors in the partition, if more than 65,535 sectors
