|The old schoolers will tell you to never flash a BIOS unless it |
is absolutely necessary. That's because of the old ways that
were required in order to flashing a BIOS. You had to make a
bootable DOS floppy disk, then add the firmware/Bios update
to the floppy disc, sometimes it didn't fit on the 1.44 Mb
floppy disk and you had to remove some DOS files. Then you
would boot up to the floppy. The A:\ drive would grind away,
brrrrrd brrrrd, brrrd brrrd...and most times the flash was
successful. The issues were that floppy disks were/are very
volatile media formats, and they were very slow.
Modern firmware flash methods are much easier. There are
downloadable *.exe files that can be used in an OS
environment to flash BIOS's, or you can make bootable
DVD/CD iso flash disks to update systems - it's pretty safe &
easy. One Dell System (I think it was a Latitude C600 laptop
series) had like 23 BIOS revisions!
You'll still want to use common sense, and to be really safe:
- Think twice before you flash a BIOS on a sick PC with
possible sick components (like bad PSU or RAM or HDD or MB level
component), unless the BIOS update specifically fixes an
issue you're seeing.
- Don't flash BIOS's w/o a PC being on a UPS (ultra safe).
- Don't flash BIOS's on laptop w/o using AC adapter (many
flash utilities will not even let you flash a bios w/o AC power
- You might NOT want to flash a BIOS's during uncertain electrical periods like mid day when it's 90 degrees outside and everyone has their air conditioners blasting away.
- Don't flash BIOS's during a bad weather or thunderstorm.
I've had two bad experiences with firmware updates going
wrong in about 12 yrs. One was on an old Quantum 5.25"
BigFoot HDD, the other was on an HP Pavillion PII p.o.s. PC.
Just my 2 ¢
Just another stupid saying...
