BIOS Updates forum

Intel 945 chipset support max 4GB of RAM but usable are less sometime,depends of system manufacturer ~3.25GB usable
From 3.25GB to 4GB are system resources.

Most batteries are so called smart battery.
Communication is done through SMBUS.
In event of defective one that must somehow to short circuit smbus signals or garbled communications.

Almost done. Still BIOS can't boot native from disks. Main problem was: -BIOS doesn't make a call to BCV (after initialization OROM resize itself but also clear any configuration,that is make so when calling BCV, OROM get his disk BIOS assigned number. -trying to make later a far call to this BCV sh...

According to what I read in PnPBIOS datasheet BIOS must make a FAR CALL to a location pointed by PnP header. BIOS will pass the following parameters when calling the Boot Connection Vector. AX 04h (which vector to hook,in may case INT13) ES:DI Pointer to System BIOS PnP Instalation check structure B...

After more testing and comparing between two cases on Intel and Dell I see some differences somewhere after PCI data structure into initialized option ROM In Intel case Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F 00000040 50 43 49 52 95 10 32 31 00 00 18 00 00 00 04 01 PCIR•.21........ 00000050 6C 00 01 ...

I have a similar card into one Intel D945GCL On both card is in same PCIe port,under 8086:27D6 Comparing RAM dumps from both I see OROM is the same after loading (after initialization). On both cases,Dell and Intel I have this (but in other range address on Intel 2ED0h-300Fh ) And using same HDD Thi...

Thanks for answering. I don't disassembled it because is beyond my knowledge. I have read PnP BIOS Boot Specifications but is not clear when Boot Connection Vector is used.Making a FAR CALL to addres pointed by BCV is done at Option ROM initialization or at moment when BIOS try to boot from device? ...

As far as I read expresscard port is just one PCI express slot with removable capabilities. So I take one 2x sata expresscard based on SIL3132, offcourse was just a simple card,just SIL3132 controller. Search in my junkyard for a flash and found one of 256k solder it to PCB and program with SIL BIOS...

seems I can't reproduce positive result,same make rom error now everytime. but believe me once worked. http://www.4shared.com/file/256568199/6 ... 5_A08.html here is uploaded rom when /writeromfile was working for me,try it.

tested and works.
use /writeromfile
pay attention is not like older -writeromfile.
1555_A08.exe /writeromfile
After that you have 1555_A08.ROM in same folder.

I've managed to build a custom pci option rom for my Dell inspiron 9400 to switch ICH7 controler from compatible to sata ahci mode. PCI registers looks ok but at boot time bios report my hdd as is was detected in legacy mode and now controller is switched to ahci so all programs can't access my hdd....

I really need some help with this,
Main request is to enable ahci and adding hpet function.
Chipset is I945PM - 82801GHM ICH7-M
Decompressed bios modules is here Uncompressed

Good news on mydigitallife split and unpack,repack modules.

Is there anybody with knowledge in intel 8051? Some dell notebook family use a embedded controller based on 8051 cpu. I don't know anything about software and reverse engineering but maybe some others can decipher what firmware inside controller do with hardware and with bios rom (which is somehow e...
