I just started hacking my webplayer. I bought a 44-pin IDE cable from badflash and bought a Fujitsu 4gb harddrive (MHF2043AT). I have set the IDE bus to Primary in the BIOS and connected the harddrive. When I start webplayer, I get the "Invalid system disk" error. If I go into the bios, I can see that the harddrive is detected correctly (with the model number), but still I get this error. The disk has two partitions, one primary containing DOS and another logical partition with no data, each of 2gb size. I was able to boot off this drive in my laptop. At the same time, I was able to connect the laptop's drive to Webplayer containing Windows 95 and successfully start the boot (aborted the boot, as the drivers will not match). So, out of the four combinations (two hard drives and webplayer and a laptop), only one combination (new harddrive + Webplayer) doesn't work. Can anyone help me solve the problem? Is it anything to do with how the drive is partitioned? Do I possibly have to change any other settings in the bios? I already tried setting the OS to DOS. Any help will be greatly appreciated.
