Hello all, nice to be here, looks like there are a lot of people with enough knowledge to help me.I've got a problem releated to memory and audio in 98se. I've installed 98se thanks to the workaround maxphyspage, which was set to 512mb. it would be working fine if I didnt use dos software ,but that's why I'm running 98se. I can't open any msdos mode windows, because it says that there is no sufficent memory. I've tried editing system.ini by adding vcache to 128mb,256 mb, 512mb, but no luck. I've installed unofficial sp 2.1b polish, but I don't know if it was installed properly,cause after reboot any dos program during configuration didn't start. Another problem is releated to my sound card. I've installed a4.06 drivers from realtek,but there was an error with ntkern and mmdevldr not loaded properly. however, when I've uninstalled it and installed an old nforce 4.27 driver, the audio is working but only partially .MIDI doesn't work and during directsound tests, I can't hear any sound on some. looks like system sounds work. directx was updated to dec2006 package. My knowledge is not good , but I would like to overcome the problems.I'm looking for your help. my specification of pc: Athlon 64 3000+ 2.1ghz 512Mb ram + 1024mb ram radeon 9550 128mb maxtor 120gb nforce 3 250gb chipset with integrated ac97 card thanks in advance, feel free to ask, if I skipped something important.
