My brother experiences a problem with his ancient PC (P2 266MHz) and I tried to help him with no satisfactory results. That is why I am posting here, in order to ask you if you have any idea that we havent thought/tried already.
Probably due to a light-storm or intense over-clocking, his PC got burned. After a lot of tests by a pc-technician, we found out that his old motherboard, the CPU, half of his memory modules and the PSU got burned.
We bought a new PSU (350W), we found a working equivalent motherboard to the old one, a working P2 266 like the old one and we kept whatever was not burned.
The problem is that the PC refuses to do anything after the intial boot-up. It finds the CPU ok, it finds the memory but gives the following message
"disk boot failure. please insert a system disk"
My brother's PC has 2 Hard disks (a 40GB new one and the 7GB original one), a CD-ROM and a SCSI CD-Writer. The OS is on the 40GB one, which cannot be recognized by the system unless we flash a new BIOS.
But no matter the boot order set in BIOS (A,C, SCSI etc) the PC seems not to care and doesnt search to see what is in the floppy drive, in the CD-ROM or in the CD-R.
I ve tried all the following combinations but with no luck:
1) all 4 devices (HD1, HD2, CDROM, CDR) and FD (floppy) connected as should, and the system freezes as it cannot recognize the HD1 without a BIOS upgrade
2) as before except HD1, and with HD2 set as primary master, I get a "please reboot" message
3) only SCSI CDR and FD, but it doesnt look for the WIN XP CD or the Win98 startup disk that I insert
4) nothing connect, I get on the start screen "Primary disk error"
Any ideas? I know that it is not worth fighting for such a system, but at least I d like to understand what is the problem! Why it doesnt boot from the floppy? Why it doesnt boot from the CDROM or the SCSI CDR?
