Did you run the BIOS updater from real DOS? You can do the HDR recovery method using a USB floppy drive.
This is difficult to say because the originals are different Name: D610-A05.exe Size: 647464 bytes (632 KiB) SHA1: D8F95961868FFAF7EB222A03753AE34D5CE27B09 Name: M20-A05.exe Size: 647476 bytes (632 KiB) SHA1: A9E3493D502F0E999EF5D24C8BF656EC1CB13252
Not directly. We'd have to hack the header so it flashes correctly. We can only attempt at making a cross-flash BIOS if your M20 has integrated Intel graphics? IIRC, the Precision M20 only comes with ATI Mobility FireGL V3100.
These old laptops are really slow and limited to 2GB RAM, so I wouldn't recommend you go out and purchase one.
Curios, why did you crossflash the D800 onto your M60? It appears that Dell kept the M60 A09 BIOS updated with the same fixes/changes as the D800 A13. M60 A09 == D800 A13 M60 A08 == D800 A12 M60 A07 == D800 A11 etc.
Really? So the M60 A09 BIOS is identical to the D800 A13 BIOS? Interesting, so there's no point in flashing the A13 D800 BIOS even though it should be newer.
99% sure the BIOS are identical aside from the model number strings. Dell did this a lot with their Latitude D8xx and Precisions M6x[xx] back in the day. Hardware-wise they offered slightly different video cards, but the BIOS would contain all the VBIOS Option ROMs.
Can confirm, i'm running the A13 Latitude C840 BIOS on my M50. It does show up properly as Precision M50 though.
I found a M20 at last for my ever expanding Precision collection, can you make me a LBA48 BIOS @tqhoang?
Sorry what I did only works with the D610 with integrated Intel graphics, not with the ATI graphics...hence it won't work with the M20.
