The Pentium Dual-Core are either 32-bit or 64-bit; see
<https://en.wikipedia.org/wiki/Pentium_Dual-Core>.  You can run Debian
12/Bookworm on with 32-bit or 64-bit.  Debian 13/Trixie only supports
64-bit.

You have to determine which version of the processor you have.  Check
in the BIOS.

If you can boot to Bookworm, then dmidecode should be able to provide
the information.  Notice the "64-bit capable" below.

$ sudo dmidecode -t processor
# dmidecode 3.6
Getting SMBIOS data from sysfs.
SMBIOS 3.4 present.

Handle 0x0004, DMI type 4, 48 bytes
