Missing Microcode for old Intel CPU

Moin,

Currently i'm trying to build BLFS-12.1 on a pretty old Dell-Latitude-D810.
This is /proc/cpuinfo:
Code:processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.86GHz
stepping : 8
microcode : 0x20
cpu MHz : 800.000
cache size : 2048 KB
fdiv_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss tm pbe nx bts cpuid est tm2
bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit mmio_unknown
bogomips : 1596.04
clflush size : 64
cache_alignment : 64
address sizes : 32 bits physical, 32 bits virtual
power management:So i'd assume, that intel-microcode file should have a name like:
06-0d-08
Unfortunatelly, i don't find such a file in the github link provided by the BLFS-Book in the chapter "About Firmware".
Is there any chance left for me to get the spectres and meltdown issues of that CPU fixed?

cheers,
WK
