Debugger General Information

4

Blocks Versus Sectors

The logical block defines the unit of information for disk devices. A 
disk is viewed by 167Bug as a storage area divided into logical 
blocks. By default, the logical block size is set to 256 bytes for every 
block device in the system. The block size can be changed on a per 
device basis with the 

IOT

 command. 

The sector defines the unit of information for the media itself, as 
viewed by the controller. The sector size varies for different 
controllers, and the value for a specific device can be displayed and 
changed with the 

IOT

 command. 

When a disk transfer is requested, the start and size of the transfer 
is specified in blocks. 167Bug translates this into an equivalent 
sector specification, which is then passed on to the controller to 
initiate the transfer. If the conversion from blocks to sectors yields 
a fractional sector count, an error is returned and no data is 
transferred. 

Device Probe Function

A device probe with entry into the device descriptor table is done 
whenever a specified device is accessed; i.e., when system calls 
.DSKRD, .DSKWR, .DSKCFIG, .DSKFMT, and .DSKCTRL, and 
debugger commands 

BH

, 

BO

, 

IOC

, 

IOP

, 

IOT

, 

MAR

, and 

MAW

 

are used. 

The device probe mechanism utilizes the SCSI commands "Inquiry" 
and "Mode Sense". If the specified controller is non-SCSI, the probe 
simply returns a status of "device present and unknown". The 
device probe makes an entry into the device descriptor table with 
the pertinent data. After an entry has been made, the next time a 
probe is done it simply returns with "device present" status (pointer 
to the device descriptor).
