I have a Aopen AP53 rev3.3,i430HX, socket 7,use AMI win bios,
support as low as 2.0V, so I upgrade from PMMX200 to K6-2-400
I download the newest bios,
can't recognize K6-2-400,only show K5-133,
I use another pc of K6-2-400 on asus T2P4(i430HX),128edo ram as standard,it runs winxp fluently.
K6-2-400 on aopen ap53, 128edo ram run windows xp rather slow,processor always used 100%.
I run setk6v3,found that write allocation and write combination are disabled,I thought this is the reason why it is so slow.
I heared AP5K is the enhanced version of AP53,i430HX, same I/O.
I flashed bios of Aopen AP5K,it is award
the pc could still boot,
K6-2-400 showes as 486DX2-66;
but cannot detect floppy;
CDROM detected while not bootable;
but HDD boot to winxp and running very fast,simillar to K6-2 on asus T2P4setk6v3 showes write allocation enabled write combination disabled.
However,if change with another HDD,then the new HDD is not bootable.
I flash back bios between ap53 ami and ap5k award several times,
problem is the same,
ap53 too slow,
ap5k can't find floppy,can't boot from amy IDE device if changed HDD.
What can I do?
Thank you very much!
