i have successfully created a unattended XP of 655 MB

now i got some additional drivers Approx. 60MB compressed will become 4 MB, if i place these under $OEM$\$1\Drivers\mydrivers, my CD will become 715 MB.

isn't there any way so that i can compress this and place somewhere, but should work like as if i have placed inside $OEM$\$1\Drivers

suppose say:- shell32.dll is compressed to shell32.dl_ (reduced size ) and it decompressed in system32 with 8MB

isn't there a simple way for this so that i can easily put my additionals drivers

yes you can compress them and then copy/decompresss them during the 'detachedprogram' portion of setup. There are a few post/ guides around for doing that.

thanks dude,

i managed to build a winrar sfx to compress all my drivers and to be extracted under %systemdrive%\drivers during t-39 stage. but one thing,

which phase of windows setup process actually starts to detect drivers ....

i got fear if this could jump th setup without detecting my drivers ..

drivers are detected shortly ater the t-39 point as I recall, so you don't want this to take to long.

does this mean that if i compressed drivers abt 250 MB resulting 80 MB, which may take 2 minute to extract meanwhile t-37 starts will affect driver detection....
