Did you use the same PSU on both (KT7-AV/KT7A) ?

Took the KT7A out of the case to do some troubleshooting with multimeter and different AGP-cards but now I'm having severe problems to even boot the whole thing... CMOS reset -> boots -> FSB to 133 -> save & boot -> back to bios, change NOTHING, save, boot -> no picture. Power cycle, reset, nothing …

Another report of bad times... Now that the pc seems to be ok i've encountered another matter. Win98/Xp gets installed without issues, so i would try a clean msdos 6.22 install, in order to create a Msdos 6.22/win98 system, after an hd formatting and partitioning using the win98 cd boot menu ( …

I have noticed some PCI slots can be more finicky than others. If possible, also try to change the PCI slot.

Did you give the 4200 a try? I haven't tested it with the Voodoo2 but it works fine with 3.

Yes, this is for the 1.0-1.2, he also has the 1.3 BIOS there... I don't know the intricacies so much of that board revision, though I will attach my modified version of his BIOS to unhide APM (disable ACPI). I did this with modbin63, and I can't share that here, you will have to find it yourself. …

Wow 1000x thanks for this, right out of the bat I was thinking the proposed solution is: throw your card out to the trashcan and buy an ISA SB16 :) Works like a charm I can confirm both the MSDOS6.22 and Win3.X drivers, the 9X was always working even with phils driver. Maybe some1 should hit …

Anybody got Voodoo2 working on Abit KT7A? Tried two different cards, different PCI-slots, original and Fastvoodoo 4.6 drivers, PCI-related bios-settings, slow CPU down to 400MHz... Nothing helps, damn thing just crash when try to run Glide. OS is Windows 98SE. Anybody? This problem is making me …

Damn, my tbred 2600+ (AXDA2600DKV3C) seems to be locked ( i cannot change multiplier neither from bios nor via software ) to my epox 8kta3 pro+...

That's a really nice setup 😀 How well does Windows 10 work though? In my experience it is slow as hell on the Athlon 64. All other OSes work just fine, including the latest Debian/Ubuntu.

I have tried the ESS Solo-1 in a much newer system (MSI MS-7253 / K9VGM-V (KM890, VIA8237A) , Athlon 64 X2 5050e, Radeon X800 XL) that still retains DOS compatibility and can be slowed down to 386 levels. It's a really nice card coupled with the X2GS or WP32 McCake.

My hypothesis is that my modern PSU, which can only output 24A on the 5V rail, is too frail. For example, I sometimes cannot boot with a voltage >= 1.5V which seems anormal. Voltage must be lowered to 1.35V for Windows XP installation to succeed.

I have modded the AXMH2400FQQ4C successfully (CrystalCPUID reports the original multiplier as 18x) however even after changing register 55h from 89 to 8D I still get a system hang when changing the multiplier or voltage in CrystalCPUID (version 2.0). Same behaviour in DOS when changing multiplier …

That's awesome! Congratulation 😀 Could you elaborate on which bridge you had to cut to get to 18x? Also, perhaps ping the author of SETMUL to suggest adding the register change you mention.

Ah I never knew that feature existed, it's pretty cool! I can confirm the AOC G2590PX can also switch between wide/1:1/4.3 and a few other modes with the > button.

After trying a number of soundfonts (listed here: Re: WP32 McCake : MT32 compatible waveblaster board) I personally find the deemster SC-55 soundfont most enjoyable, although I never had a SC-55 or SC-88 so I can't really compare, but it seems the most "whole". What do you think dreamblaster?
