My first notebook that can run SP2019 on-premises

I have to switch back to windows because almost all verilog toolchain only work in windows. And I bought MSI Prestige-15-A10X which has 32GB ram and 1TB nvms ssd, it is only $15300 HKD, super valueable. It is the first notebook which i can run a SharePoint 2019 VM locally.

x86 disassemble預研成功,感謝Rod Pemberton朋友在alt.lang.asm上面的幫忙,原來Intel instruction雖然係CISC但可以在未decode所有Byte之前把Instruction切割出來。還有,切割比我想像人來得簡單。我現在的問題就是,RISC的所謂固定長度指令好像不是傳說中所說的巨大優勢。
