Anders Petersson: I have cataloged the bios settings from the unit we received back from outside calibration, and coincidentally just had another unit in our facility with a dead CMOS battery. When I replaced the battery in that other unit, it suffered the same issue with not retaining changes to the settings (we use Fahrenheit and it repeatedly reset back to Celsius at every restart or power cycle). After comparing the bios settings between these two units, I see that some of the other default settings need to be changed. for one thing, AHCI mode is not the solution, it needs to stay on IDE mode, but some of the other non-default settings are what allow the units to boot past the "jumping to" message and also save the settings. Note: There are two different hardware versions of the VGA optica units... earlier models used a motherboard with PS/2 mouse and keyboard ports in the rear corner next to the ethernet port which have been covered up by an adhesive plastic panel; these units have a BCM WhizPro bios. Later models use a newer motherboard with USB ports stacked under the ethernet port in the middle of the rear of the unit; these units have an American Megatrends bios. These bios settings are for the later model without PS/2 ports. The USB ports are blocked by a small metal shroud that is spot-welded in three spaces inside the chassis of the unit. If you open the unit and carefully shimmy a relatively robust flat-head screwdriver between the chassis and each welded tab of the shroud, you can pop the welds with some force and save yourself the hassle of taking the whole motherboard out... you may need to remove the PCI card, though. These were the settings that were different from the default on our unit from outside calibration: 32Bit Data Transfer: Enabled PCI IDE BusMaster: Enabled LAN Option ROM: Enabled (likely irrelevant, but was enabled on the unit received from cal) Serial Port3 IRQ: IRQ11 Serial Port4 IRQ: IRQ11 Serial Port5 IRQ: IRQ5 Serial Port6 IRQ: IRQ5 (for whatever reason, these pairs of serial port entries in the bios need to have conflicting IRQ values) You could also set the "Flat Panel Type" to 1024x 768 18-bit instead of 1366, this will ensure POST and BIOS don't try to display off the screens Hopefully any of this is useful. --- Code: ---Primary IDE Master Type: Auto LBA/Large Mode: Auto Block (Multi-Sector Transfer): Auto PIO Mode: Auto DMA Mode: Auto S.M.A.R.T.: Auto 32Bit Data Transfer: Enabled IDE Configuration Configure SATA as: IDE PCI IDE BusMaster: Enabled Quick Boot: Enabled Full Screen Logo Display: Disabled Bootup Num-Lock: On Wait For 'F1' If Error: Enabled Configure advanced CPU Settings Max CPUID Value Limit: Disabled Execute-Disable Bit Capability: Enabled Hyper Threading Technology: Enabled USB Functions: 8 USB Ports USB 2.0 Controller: Enabled Legacy USB Support: Enabled Audio Controller: Enabled GbE LAN Boot: Disabled LAN Option ROM: Enabled Serial Port1 Address: 3F8 Serial Port1 Mode: RS232 Serial Port1 IRQ: IRQ4 Serial Port2 Address: 2F8 Serial Port2 IRQ: IRQ3 Serial Port3 Address: 3E8 Serial Port3 IRQ: IRQ11 Serial Port4 Address: 2E8 Serial Port4 IRQ: IRQ11 Serial Port5 Address: 2F0 Serial Port5 IRQ: IRQ5 Serial Port6 Address: 2E0 Serial Port6 IRQ: IRQ5 Parallel Port Address: Disabled Watch Dog: Disabled GPO1 Data: Low GPO2 Data: Low GPO3 Data: Low GPO4 Data: Low DVMT Mode Select: DVMT Mode DVMT/FIXED Memory: 256MB Boot Display Device: CRT + LVDS/DVI Flat Panel Type: 1024x 768 18-bit Output LVDS Format: 18 bit Initate Graphic Adapter: PCI/IGD ACPI Aware O/S: Yes Suspend mode: Auto Restore on AC Power Loss: Power On Advanced Resume Event Controls: all disabled --- End code --- |
