umm or is it a typo ? mine realy is 5.03 (search brought me here)
tip..if he changes to xp in the support hp site then checks bios version.
it might be diff version with no slic 3.19 for xp ?
instead of vista bios 5.03
like this a1726x pavillion P5LP-LE (Leucite3)
i modded with awardtool 1.52 in
ISA mode added HP SLIC2.1 and SLP
in tool shows AWARD BIOS v6.00PG
P5LP-LE Motherboard BIOS Update
2007-10-02 , Version:5.03, 1.37M sp35172.exe
ftp://ftp.hp.com/pub/softlib/software9/C...p35172.exe
but im scared to try it

friends pc. its not dos flash
its winflash.exe with installer.exe next to it and WinFlash.sys
i saw flashrom has support for Pm49FL004 but no T at end but im almost sure it works.
or should i stick with installer.exe to run the winflash.exe with the 503.ROm as the slic moded renamed ?
also i wonder if i could reflash with pins soldered if bad flash.. as i seen a few traces to a missing pins group of solder pads like a JTag port next to Pm49FL004T (no socket..soldered on mobo)
