Hi all,
I received several requests for changes to the QDI Titanium IB+ BIOS. So I have been working on a patch J.3 BIOS update for this jumperless board, and I made some progress.
@JustJulião,
I was able to add IDT WinChip 2/2A/2B support. The new BIOS now properly detects these IDT models and displays them correctly as IDT WinChip 2.
The SpeedEasy CPU SETUP code is very difficult to change so the multiplier settings are still the same as for the WinChip C6 but they work the same way on the WinChip 2 and 2B. Only for the WC-2A, you have to use the translation table I put up earlier in this thread, when setting the multiplier.
@S0N1C,
I read your request about Tillamook support and I’ve started to look into that.
The BIOS detects and displays the Tillamook just fine but support for this CPU is completely missing in the SpeedEasy CPU SETUP, just as you reported. Instead, the BIOS sets the board as for a standard non-MMX Pentium with a single voltage rail with 3.4V! 🙁
The first step will be to change this to a dual voltage Pentium MMX setup. This shouldn’t be too difficult. But secondly, the default 2.8V setting for the MMX has to be lowered to 2.0V for the Tillamook only. This will be a challenge…
Note that the 2.0V Vcore and 3.3V Vi/o are the lowest possible settings on this board due hardware limitations.
@Sphere478,
You did the interposer for the Tillamook and other socket 7 CPUs, so could you help us with the multiplier settings on the Tillamook? Without hardware changes, this jumperless QDI BIOS can control the BF0/BF1 pins of the original Pentium MMX only. The Tillamook BF2 is therefore out of reach without an interposer.
Can you tell us which multipliers are possible on the Tillamook by using these original BF0/BF1 pins only?
To all,
Other bugfixes that I will add to the patch J.3 BIOS:
- A fix for the second 64GiB HDD limit bug. This will fix a hang when initiating drive detection via the IDE HDD DETECTION menu in the BIOS on a drive > 64GiB.
- An improved 32GiB HDD limit bugfix that allows drives > 128GiB to be attached, so at least 128GiB can be used from a larger drive (maximum 640GiB).
- A fix for the Win98 UDMA bug. This allows ATA66/100/133 drives to work correctly in UDMA mode 2 (33MB/sec) on the on-board IDE channels by enabling DMA mode in device manager. Without this fix, these faster drives would revert to PIO mode 4.
I will be back with an updated progress report soon. 😉
