http://www.amilo-forum.com/topic,273,-Amilo-A-1630.html this User RaptorMX says he made a modified bios, that supports turion now, for Amilo A1630 which is that Laptop with this mainboard 258ka0.
I really don't know what you mean by microcode, or what a microcode is.
So the fact is, that Bios 1.05 from 258ka0 still doesn't detect AMD Turion. It allways says "unknown cpu". Also your first mod didn't change something. So maybe there's allready the turion microcode in this bios 1.05 but something else doesn't work!? Then in all those bioses there must be all these 3 different microcodes, right?
Or wtf is the difference then between those bios files, that support this cpu, like
P50CA (
http://www.uniwill.com/UserDownload/P50C...OS_107.zip ) and
255ki3 (
http://www.uniwill.com/UserDownload/255K...i3_105.zip ) from Uniwill website and my bios file
258KA0 (
http://www.uniwill.com/UserDownload/258K...a0.105.zip ) that is the only one that doesn't support turion???
The only difference is that first two have SIS760 Chipset and mine has SIS755 Chipset. That's why i send you the links to those other mainboards, that also have SIS755 Chipset.
If you go to Fujitsu Siemens Page, you'll find Notebook Amilo A1640. For this Notebook a1640 (Uniwill 255ki3) you'll find several Bios Files there. They clearly write, that at version 1.03 Turion support was added. So maybe you can compare bios 1.02c (
http://ul.to/qjdqnp ) and 1.03c (
http://ul.to/yoaebe ) of Amilo A1640 to see, what exactly they changed and you can do this change also with my A1630 (Uniwill 258ka0).
Other stuff that i found are two mods for k8s8x with SIS755 Chipset:
