[Request] Dell Latitude D530 Intel T9x00 Support

[OliverG]

No luck,

Acted a little different this time Dell Bios Splash screen displayed white progress bar went from left to right then went to a black screen with just a white cursor flash at the top left of the screen, no text was shown.

Could only get this to show the once though after trying again back to just solid power light if no hdd in or sold power and flashing hdd light if drive is in with nothing on the display.

Can you disable displaying "white progress bar" to read POST messages? Don't reset CMOS before new CPU installing.

Thanks for all your efforts DeathBringer but going to keep the T7500 in for now, I had a look in the bios options 
now the T7500 is in and dont see any option to show the full post messages, and I only tried to reset the cmos
after I could not get it to boot normaly on the T9500.

I've found other module with CPU checking: 04_6. I can't patch it. Because D530 BIOS uses the constant but needs the variable.
Please download RWEverything. Try portable version.
Press CPU MSR registers button, press User list button or F5, type a=0x19C, press Add, press Done.
Post a value of MSR with address 0x19C.
It's IA32_THERM_STATUS. So it can't prevent booting. Only BIOS show temperature of CPU with a difference of five degrees.

I've found second place with CPU checking in module 02_4 and patched it. Please try my 4th mod.

No luck, Same as other attempt below

Was thinking Dell added support for the T9500 and other Penryn cpus on the Latitude D630 from
Bios version A07 onwards, would it help to compare the difference in say the A04 and A07 bios to see
the secret to getting this cpu to work on the D530.

Good advice! I've found two new interesting place in 04_6 module and patched it. Please try my 5th mod.

No Joy DeathBringer still no boot, That will have to be the last try for the moment as I have sold off the cpu on ebay now so need to send it off, hopefully someone else will want to carry on your good work in the future.

Going to stick a T7700 in its place as that was at least a dell combo for the D530.

OK. I give up. Too many changes in BIOS are required.

Hello Bios Mods Forum!

I have spent the last day trying to get my trusty old Dell D530 to run a T9500, it is not on the supported CPU's list but I thought it would be fun, I have a lot of these laptops and they fit my needs perfectly. I've never edited a bios in my life, but I do a lot of hex editing to unlock airbag units for cars and immobiliser data etc.

So far I have worked out how to extract the bios rom file from the Dell exe's, in hdr format with the header.
Worked out how to swap one of the microcode entries to match my T9500.
Worked out how to modify the checksum to be correct.
Got updating the bios via dellbiosupdate in linux sorted.
I can make the self installing windows EXE with DCCU.

But it won't boot
It does nothing, just powers up and HDD activity light flashes in 2 pulses quickly.

I've had the cpu in and out of a couple of D530's, with various alterations to the microcode. 1 dimm fitted, front or back, battery in/out, hdd etc.

Here is a CPUz of my mainboard:-
   

My bios files look like this with intelmicrocodelist.exe :-

Here are the selection of standard and modified bios files, and the injected microcode :-


  dell d530 bios microcode.zip (Size: 1.59 MB / Downloads: 10)



And these are the instructions for resolving the checksum for the bios :-

Code:

Select block 54 to 200053 and calculate crc32 checksum of it.
Apply NOT to the crc32 checksum, then reverse the order of bytes, e.g. 01 02 03 04 = 04 03 02 01
This reverse order checksum is stored here:- 200054-200057
Now select 54 to 200057, and calculate crc32. If correct checksum, crc32 = ffffffff.
Also crc32 of the whole file = ffffffff.

My CPU is stamped on the front:-

Intel '06
5808B317  SLAYX
FF80576 T9500
2.60 / 6M / 800

(I think this is a cpuid=10676)

My mainboard chipset is a GM965 which is noted to support the T9500 cpu.

Both CPU's have the same FSB, TDP, and pretty much the same spec otherwise except:-

the old 65nm Mermon runs 1.075V-1.250V
the new 45nm Penryn runs 1.000V-1.250V

My RAM is PC2-5300S-555-12-E3 so that only runs at 166.6mhz - could this be a problem? I don't think so but I'm no expert.

Dell bios's are a pain I'm getting the impression....
But can anybody help me push this any further towards success
