Umh right now i am using a 500W semi-modern PSU with 45A on 5V, is it good?
Anyway little update for those who can help me! im so desperate 🙁
So i bought that ASUS A7S8X-MX on eBay, came today and had just time in a rush to plug it "as is" (on cloth table, no case just on fly setup) and the mobo it works. I installed fast the ESS and the HDD with MSDOS 6.22 inside and......almost still same problem.
The southbridge is a SiS 964. Now at the loading driver Allegro-1 screen i get TDMA (btw, can someone kindly please explain me in a short and simple words what are DDMA and TDMA, and what are the differences or\and which one is better?) but i get almost the same issues of before:
No SFX in Blood, Duke3D (any Build engine game, both in 8bit or 16bit). No sounds on Epic Megagames titles (Jazz and Epic Pinball, Jill of The Jungle works tho) Or maybe im r3t4rd and i am really missing something. All i know is that on that specific 2006 Asus it all worked flawlessy, despite it was a PCI-Express and DDR2 and Socket 775, kinda too much modern.
Seriously i feel i wasted 34€. I mean is also my fault that i rushed to buy this mobo just because it was from 2004, had AGP and Socket 462.
Fact is, i noticed unplugging the HDD (so start without nothing) that i can see the IRQ screen right after the invalid boot device blabla. and i can see that Multimedia Device is under IRQ 10. How the hell i can set it up on IRQ 5? maybe this could be the problem. I've already pratically disabled everything that takes resources (Floppy, Serial Ports, Integrated Audio, Ethernet, USB... everything.)
Another fact is with my enormous disappointment, this bios is VERY VERY poor (is the one that came with, the 1005, the latest one i think) what if i downgrade it?
There are really few options, under CPU you can only read the name and Mhz: nothing else. No OC. No possibility of disable L2 cache. Just nothing.
Also, looks like there is NO possibility of choose manually the IRQ assignment. the 2006 Asus had it (the screen with all IRQ and like "ISA Legacy\Reserved", this from 2003-2004 no. Really?
There's an option to set like IRQ to Auto or Manual, but looks like nothing change, no unlocking other options. One of the most poor asus bios i ever seen.
Please help me, because on some other games that in a rush i tried, everything just worked fine (Doom, Wolf3D, Another World, Prince of Persia all worked okay) but is pointless to have a system where sounds work for half of games. The set blaster is A220 I5 D1 T6, but on the Allegro-1 boot up driver screen i get IRQ 10 or IRQ 7, T4 and D1.
Please anyone, i just want to all work like on that 2006 Asus incredibly did.
these are basically the only options aviable on bios:
