Searching for ICS952603 Datasheet
Posted on 2023-04-17, 17:40
Hi, all. I'm in search of a ICS952603 datasheet. It's a PLL chip, which was used in P4\P4-M era motherboards. Any info on that IC would be highly appreciated.

Good work ! Yes some older ATX boards have issues with newer ATX psu. Have a few old ATX boards that refuse to start with any newer ATX spec PSU after 2005. Something to do with the ATX12v spec board is expecting being 2.01 or earlier afaik...though a few listed as 2.03 do work on those same boards …

In because im interested to see if this can be safely flashed to retail gigabyte bios. I have the same board with compaq bios. Don't see a reason why it wouldn't work. Just checked with gigabyte's flash848 utiity - the BIOS flashed and works fine (F5 revision). But I cannot recommend doing that …
GA-5SMM - question about BIOS, PSU and brand
Posted on 2023-04-13, 14:22
Hi, I got my hands on a motherboard, which was meant to be scrapped for parts and presumed to be dead. After replacing faulty caps, busted regulator and transistors, I've been able to get it running. This is a model GA-5SMM, which seems to be a Gigabyte brand motherboard, which was also used in …
Re: dISAppointment - LPC to ISA adapter - ISA on modern motherboards

I take my hat off to you, sir! Nice work! I've designed an adapter that uses the Fintek F85226 LPC-to-ISA bridge to allow you to connect ISA cards to (theoretically) pretty much any motherboard, as long as it exposes the LPC bus somewhere and has a legacy BIOS or CSM. Both Fintek F85226 and Winbond …

@Paul_V Thanks! Uploaded the full 2MB dump here. edit: also, what address should I trim up to? I'm not sure. The BIOS is at the very end of the dump - the rest is FF I've attached a trimmed BIOS file. You practically just cut excess FF's from the beginning of the file until you reach exact 256KB in …

What tools would be best to use for a BIOS dump for the weecee? You can use BIOSMP utility from DM&P (see the attachment) Also, check that you are running in real-mode just in case. The dump size will be 16Mbit (whole size of the flash chip). To use it in amibios editor, you'll need to manually …

Well, what started as in impulse purchase now is beginning to shape into my personal dream-build of all times. By using CPUSPD utility (KUDOS to kalohimal!) this motherboard becomes the most versatile DOS gaming machine. 1) 852gm gpu does have 3d support (idk how good though, did not test) 2) 852gm …
Re: How about newer Dell monitors?

While I do not own U2421E, I'm currently using Dell U2412M. As far as I can tell they seem to be similar even in menu structure, both are 16:10 and both have scaler menu settings. My U2412M is more than decent. You can choose between 16:10, 4:3 and 5:4 which makes scaling easier. Does the job better …

I think it's a BIOS issue so I'm hopping we'll get a BIOS fix from ICOP. is the ICOP BIOS based on the Seabios code? do they share the source code (i think they need if its Seabios due to licence stuff) the "TinyLlama (Vortex86EX SBC)" project uses its own Seabios build (but can also use the …

Got an answer from ICOP, regarding L1 and divider on DX\DX2 (and probably MX too). Not an encouraging one. Quote: "It's the hardware limitation due to internal PLL (Phase-Locked Loops) design mechanism, the L1 cache must enabled in order to make internal variable clock divider work." Still in the …

I'm already quite desperate, today I made WeeCee revision 0.4. Unfortunately the BIOS does not see the SD card. I have rechecked the paths and everything is fine. Does anyone have any experience of what this could be? According to the schematic there should be nothing wrong. Thank you for any help. …

EBOX-3350 with Vortex86DX2 proved to be even more stubborn. Clock division seem to affect performance even less and disabling L1 Cache throws clock division entirely out of the window. UPD: I just remembered, that PCI clock on VDX defaults at 33,3(3) Mhz, but there is a strap to run it at 66,6(6). I …

Awesome job there, thanks! My cherished dream is to see ESS IC's reverse engineered, like genuine Yamaha OPL3. A real shame it did not see it's full potential used.

@Paul_V It seems I missed a few bytes - all the IDs should be 18CA 0040 now. uploaded new 32KB ROM. Didn't work either. It is bootlable only if I swap the ROM with the same ID. What do you think the odds are that ICOP or DMP will actually help and provide a fix for the incorrect SD card size issue? …

tl;dr I flashed my board, too, with Xilinx DLC7 cable. Hi! Glad this worked out for you.

Was this Original VGA BIOS? or my modded 32KB VGA BIOS? For the driver I linked Use my modded BIOS My modded one should have a different Device ID of 18CA 0040 so the killbill driver should be fine to install on it. Can you check whether the BIOS mod successfully changed the Device ID? Modded 32KB. …

@Paul_V Any luck recovering from that bad experimental VGA BIOS flash? Hi, sorry for a bit of a delay. Voodoo resurrection rituals requiring proprietary connection to the outworld are long and tiresome without an appropriate connector. I've just reverted the BIOS back to the one with 32KB ROM. …

@Paul_V I'm assuming just open winflash.exe - I'm guessing just select the modded ROM and flash it? My theory is that the extra BIOS code in the 64KB ROM is what allows 3D to work? needs testing to verify. If the BIOS mod then works I'll send you the Volari V5/V8 driver. Vortex uses own flash tools …
