>Description:
when using sysinstall for automated install (using install.cfg), or from command line, the partition=<SIZE> option of diskPartitionEditor creates a partition of type 0x03 instead of 0xa5.

The command line problem is no big deal, as fdisk can be used, but for jumpstart,
It's an absolute PITA.
>How-To-Repeat:
easiest to demo from command line:

Start by erasing all of MBR

[brj1-sut]atkstat# dd if=/dev/zero of=/dev/ad8 bs=512 count=64

then use sysinstal to create partition

[brj1-sut]atkstat# sysinstall debug=YES nonInteractive=YES  disk=ad8 \
partition=100G bootManager=boot diskPartitionEditor diskPartitionWrite

and use fdisk to view result

[brj1-sut]atkstat# fdisk /dev/ad8
******* Working on device /dev/ad8 *******
parameters extracted from in-core disklabel are:
cylinders=969021 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=969021 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 3 (0x03),(XENIX /usr file system)
    start 63, size 209714337 (102399 Meg), flag 0
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 1023/ head 15/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
