It is Pentium MMX 233 MHz class notebook. At first boot I got "CMOS checksum error" where I could propably enter to BIOS and change settings (suggested me to push F1 or something). I have turned it off and replaced 1220 battery to 2032. At second boot with new battery I didn't got an error but I don't know how to enter to BIOS. I have tried all F1-F12, ESC, Del and none works 🙁 Any ideas ?
