@jumper Thanks! I'd downloaded that but I thought I'd ask for D00748-001-002.exe or 5.1.0.2800/2700/2100, since these later drivers may offer some functionality improvement. Just in case you or anyone else downloaded any of these files back in the day and still has them, it'd be awesome if you could share here. But if not, it can't be helped

@farfigs11 @FantasyAcquiesce @jumper Sorry to disturb you guys, but do you still have any of these softwares: D00748-001-002.exe, or Widcomm 5.1.0.2700 or Widcomm 5.1.0.2100? All of the links are dead and I'm trying to get a hold of any of these to get bluetooth functionality

@SweetLow Dude you're a wizard! After running that BAT file the game performance is back to same levels as it was with 2 Gb RAM. I feel stupid for just giving up and abandoning this thread way back. I should have followed up with you. I want to know a few things if it's okay with you: 1. Any further steps you think I should take, apart from adding the .BAT code to autoexec? 2. Suppose I add 3 more RAM sticks, taking up the total RAM to 24 gb (since I want to dual boot this along with Win10). In this new 24 Gb setup, would the .BAT code remain the same? 3. Is there any resource from where I can learn exactly how all this memory addressing, MTRR, code in .bat file works? I'm genuinely curious to get up to same level of knowledge, if feasible

Sorry for the delay. I pressed F8 -> command prompt only. Then navigated to msr/DOS_RM, pasted the .bat there. Then I executed the .bat file. Typed "win" and windows started normally. Then I ran msr/Win9x/MTRR_VAR and here is the output: MTRRcap Register: 000000FE 0000000000000D0A Variable MTRR Count: 10 Fixed MTRR Supported: TRUE Write-combining (WC) Memory Type Supported: TRUE SMM Memory Range Registers (SMRR) Supported: TRUE MTRRdefType Register: 000002FF 0000000000000C06 Default Cache Type: 06h Writeback - !!!

Thanks. I have a few clarifications: regarding point 1, do you mean I should press F8 -> start in command line only mode -> run the .bat above -> and then type "win" and generate output for MTRR_VAR? And regarding your point 3, I saw the linked thread. For now I won't install the vmm4gfix patch. For now I will just share the MTRR_VAR output with you using the procedure I said above. Hope that is fine

So with the triple 4 gb sticks, a weird effect I was seeing - the BIOS POST screen itself would report either 4 gb RAM (even with three 4 gb sticks) or 8 gb RAM - depending on which order I put those sticks in the slots even though the sticks are same brand and same model. This was frustrating me so I changed the sticks. Now it is - Slot A - one 4 gb 1333 RAM, slots B and C - 4 gb 1600 RAM. The two 1600 4 gb sticks are the same model, but obviously different from the 1333 4 gb stick in slot A. With this config the BIOS correctly reports 12 GB memory during POST.

Absolutely interested in trying to correct it. Just let me know what to do. One thing though - I don't have your level of technical knowledge on this, so you'll have to phrase your instructions so that a layperson like me can understand.

Okay so I'm attaching output for 3 different configs -> 1+1 gb (identical sticks) dual channel. 4 gb single channel. And 4 + 4 + 4 gb (identical sticks) triple channel. Reproducing what's written on the RAM stickers for the two types of sticks: 1. Kingston 1GB 1Rx8 PC3 - 10600U - 9 - 10 - A0. (next line) HP497156 - D88 - ELFWG 9995402 - 049.A00G.

Sure, give me a few days to test this out and get back to you. Will be out for vacation for a few days

True, but even with just a single 4 gb 1333 MHz stick, the same slowdown behavior happens. Win98 works in strange ways from what I've seen - components that work perfectly in other setups, may suddenly start giving problems when used together. e.g. this RAM related slowdown doesn't happen if I use the same RAM, GPU, etc. in a G41MT-ES2L board

Unfortunately, none of these solutions helped. I think it may be a quirk with my particular hardware setup (X58 chipset more specifically) Thanks a lot mercury. This didn't resolve the issue (maybe some issue with Intel X58 or Gigabyte board that I have (EX58-UD4))

Oh my bad, let me update that thread with the results for that particular issue

The EAX (in fact sound hardware acceleration) related issue is independent of the nvidia driver - same issue happened even if I have an ATI X850. No longer though, since I removed IRQ steering. And about RLoew's patches, yeah - as far as I remember I have PATCHMEM and TBPLUS installed - though I did check the EAX related issue before installing TBPLUS and it was still there, so I guess TBPLUS isn't at fault

Under the BIOS PCI devices listing, both are shown as having IRQ 5. In Win98 device manager too, both still have the same IRQ 5. And yet now everything works perfectly. Very strange and I don't have the first idea what's going on. Another interesting thing - before when I played Hitman Contracts with EAX enabled (SB Audigy 2 ZS), after a while the sound would start tearing and repeating (as if some sound buffer underflow or overflow happened). After this IRQ steering related change, even that sound problem went away. As I said, very weird..

@SweetLow Hey man, thank you so much for giving me the hint of IRQ Steering. I looked it up online and found that IRQ steering settings can be found in PCI Bus device settings. So I went to pci bus properties in safe mode, then in settings tab, under Device enumeration, changed from "Use Hardware" option to "Use BIOS" option. Left the "Override Bridges" check box unchecked. Then in the IRQ Steering tab, I just unchecked the "Use IRQ Steering" check box (this also disabled all the sub-options: Get IRQ table using ACPI BIOS, Get IRQ table using MS Specification table and Get IRQ table from Real Mode PCIBIOS 2.1 call). Then after restarting, both the VGA driver and SMB via LAN access works perfectly. I admit I don't have the least bit of idea what those options meant. Maybe I only had to disable one or two things or suboptions. I'll test with games further and update here if anything got broken after my changes
