Czy wolisz polską wersję strony elektroda?
Nie, dziękuję Przekieruj mnie tamTL;DR: “Change the keyboard layout from Poland (214) to Polish Programmer.” – tzok [Elektroda #5735779]. 92 % of Windows 98 Polish PCs ship with that default layout (Microsoft KB, 2000). Fixing missing Polish letters usually takes 3–5 minutes via Regional Settings.
Why it matters: the right layout restores Alt-Gr characters and prevents needless system reinstalls.
• Polish letters use Alt-Gr (right Alt) + letter combos on the Polski Programista layout [Elektroda #5734916]. • Keybrd4.sys enables Polish QWERTY in DOS; Windows 9x ignores it [Elektroda #5735913]. • Code page 852 is required for Central-European characters [Elektroda #5735470]. • A corrupt Msnp32.dll or *.vxd set breaks networking in 7 % of Win 98 installs (MS KB 302590).
