Using the Removable Hard Disk
Boot Disk Partitions

SPARCbook Portable Workstation User Guide
SPARCbook 3 models use a SCSI removable hard disk drive which is
labeled “Series 2” and has switches that set the target ID. SPARCbook
3000 models use an IDE removable hard disk drive which is labeled
“IDE” and has no switches. The two types have different connectors so
that it is not possible to connect the wrong type of drive to the wrong
SPARCbook model.
ò
SPARCbook 3
The SPARCbook 3 Series use a removable SCSI hard disk with a
switchable SCSI target ID, which is factory set to 3. This means that
device files for the disk slices are at
/dev/c0t3d0s
n
, as shown in
Table 6-1. A different SCSI ID can be used for the boot disk, if required.
For example, if the disk ID were set to 0 and partitioned as shown in the
table, then the device files would be at
/dev/c0t0d0s
n
.
ò
SPARCbook 3000
The SPARCbook 3000 Series use a removable IDE hard disk drive
which has a fixed ID. The factory installed operating system assigns this
drive as target 0 with the result that the device files for the disk slices
appear at
/dev/rdsk/c0t0d0s
n
as shown in Table 6-1.
Main Memory Upgrades and Disk Partitions
é
The sizes of
save
and
swap
partitions on the boot disk are related to the
main memory capacity of your SPARCbook.
é
The main memory is provided by two single in-line memory modules
(SIMMs) which are accessible through the battery compartment. This
makes it easy for the end user to perform memory upgrades without using
special tools or equipment. However, if the capacity of the main memory is
increased then the disk’s partition map must be changed to increase the
sizes of the swap and save partitions. See “Upgrading the Main Memory”
