Hi everyone, who think about "how to." do r9 m290x or hd8970m or 7970m to work
with iMac 27 2009 and 2011 year.
sorry for my english.
today i had to start new thread to write all solution to upgrade iMac 27, 2011 year with r9 card.
i have a dissasembled iMac 27 mid 2011 year, with few amd card, (7970m , 8970m, and r9 m290x 2048 editiom from MSI)
i ready to find solution to help anyone who want do with their iMacs tips, to upgrade to new graphics card.
i have a solder station,
flasher, (to flash 128k eeprom)
very interesting fact,
that Retina iMac 27 used chip
similar with all the 7xxx series,
and written by EFI driver works well with this device.
I have an idea
find the dump and try to find the video module
to make a discrete card
r9 m290x 2048mb from MSI, MXM-III
I tried to collect my EFI BIOS
based desktop 7970
editing device id
and other conditions, to try
with this driver. but it failed.
driver apparently written only
for desktop chips 7970
not suitable for the mobile version
because they themselves are different chips.
It can of course still have the hidden things
which I do not know
for example in the main firmware of the IMAC?
I think so, if the video card
No EFI, and she has the original
with his mother bios,
IMac anyway to give the image
unless of course there is a driver.
why this question one
I decided not to raise this issue
and try to solve?
Ladies and gentlemen,
Rominator, tell me your opinion
regarding this problem,
whether it makes sense to go and look for a solution
there is a great desire and technical possibilities
for example to try to collect the EFI, to the mobile version of 7970 and r9 m290x
Is there no part of the EFI
Mobile 7xxx families?
or will have to disassemble the iMac EFI from 27 Retina
to stand still,
and try to solve the problem,
I think, and I am sure, that many people will be very excited about it.
