the cdrom developed a reading trouble and i got the cdrom replaced with dvd/cdrw
i checked for its reading and writing ability when i collected from compaq service center.
recently i was planning to repartition the hard-disk and install a boot manager; when i tried to start the machine with DOS boot CD (after setting the options in bios: CDROM/Harddisk), it still started with Windows xp on harddisk.
local contact in compaq says because it is CDRW, bios is failing to note that; i am not sure of this explanation
my bios details are:
Phoenix bios4.0 Release 6.0
Hewlett-Packard Presario 2100 Bios
Chip set ALI M5237 REv3
