Published 2002-03-05 as upgrade sp20617.exe for Compaq Presario Desktop PC 7994 / 5700T (http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=35293&lc=en&cc=us&dlc=en&product=94565&os=228&lang=en)
In order to make Compaq flashtool work, I added Philips wnaspi32.dll v22.214.171.124 (http://www.storageupdates.philips.com/files/cdrw/Philips_PCRW804_R_RW_8x4x32_Upgrade_to_2.5.zip)
Neither Compaq nor Philips flashtool worked by itself. Working flashtool created by adding Philips wnaspi32.dll to Compaq package.
