Hi. Bought a mystery 'non runner' on eBay and struggling to get it working.
Specs of build:
Motherboard: M571LMR V5.1
CPU: Pentium 1 133MHz
RAM: 1 x 256MB 133
GPU: Onboard 1MB
System gets to: "Checking NVRAM...update ok!" then freezes. No NUM LOCK, no entry to BIOS, no attempt to seek boot drive, just endless blinking cursor as seen in picture:
Things I've tried:
- Different CPU, same behaviour with K6-2 and 6x86
- Different RAM, smaller capacity
- New CMOS battery
- CMOS clear
- Keyboard via DIN port and via USB addon
- No keyboard or mouse
- Added 2MB PCI graphics card, same behaviour
Completely stumped and any advice would be most welcome!
Thanks!
