Nur mit Win\u00addows XP<\/span> und \u00e4hn\u00adli\u00adchen gab\u2019s Probleme.<\/p>\n

Nach mehr als einem Monat Tap\u00adpen im Dun\u00adkeln gibt\u2019s nun eine m\u00f6g\u00adli\u00adche Erkl\u00e4\u00adrung<\/a>: Ryzen hat ein Pro\u00adblem mit VME<\/span><\/a>. Au\u00dfer in unse\u00adrem eige\u00adnen Forum gibt\u2019s offen\u00adbar auch in ande\u00adren Foren wie Red\u00addit<\/a> oder AMDs eige\u00adner Com\u00admu\u00adni\u00adty<\/a> \u00e4hn\u00adli\u00adche F\u00e4l\u00adle. Das Pro\u00adblem liegt nicht an der Virtualisierung:<\/p>\n

To be clear, the pro\u00adblem is not at all spe\u00adci\u00adfic to vir\u00adtua\u00adliza\u00adti\u00adon. It has been con\u00adfirm\u00aded on a Ryzen 5 1500X<\/span> run\u00adning FreeDOS\u2014which comes with the JemmEx memo\u00adry mana\u00adger, which enables VME<\/span> by default. Until VME<\/span> was dis\u00adab\u00adled, any attempt to boot with JemmEx fai\u00adled with inva\u00adlid opcode excep\u00adti\u00adons. After dis\u00adab\u00adling VME<\/span>, Free\u00adDOS work\u00aded normally.<\/p><\/blockquote>\n

Das bedeu\u00adtet, dass 32-Bit-Win\u00addows-Betriebs\u00adsys\u00adte\u00adme ab Ver\u00adsi\u00adon 4.0, die die Vir\u00adtu\u00adal 8086 mode enhance\u00adments nut\u00adzen, der\u00adzeit Schwie\u00adrig\u00adkei\u00adten haben, unter AMDs Ryzen zu boo\u00adten. In der Pra\u00adxis d\u00fcrf\u00adte das wenig Rele\u00advanz haben, denn wer instal\u00adliert schon ein 32-Bit-Win\u00addows, das maxi\u00admal 4 GiB RAM<\/span> adres\u00adsie\u00adren kann, auf einem Ryzen-Sys\u00adtem? Daher trat das Pro\u00adblem bis\u00adher nur in vir\u00adtua\u00adli\u00adsier\u00adten Umge\u00adbun\u00adgen auf, wo Anwen\u00adder ver\u00adsuch\u00adten, alte Sys\u00adte\u00adme in einer VM<\/span> zu star\u00adten, um dort irgend\u00adwel\u00adche Spe\u00adzi\u00adal\u00adan\u00adwen\u00addun\u00adgen zu star\u00adten. F\u00fcr Vir\u00adtu\u00adal\u00adBox scheint es bereits einen Work\u00adaround<\/a> zu geben f\u00fcr die Problematik.
