Forum: EasyBoot Topic: don't boot from cd in some systems started by: suwon235 Posted by suwon235 on May 24 2004,09:10
Hi,I made iso boot image by easyboot and added some files by ultraiso. It boots fine in some systems though displaying the message "No Emulation". But in some systems, it doesn't boot from cd displaying "non system disk" when i select only cd rom as boot device. I've not found the system difference why it boots well in some systems but not in others. could you help me, please? Posted by mrmagic on May 24 2004,17:53
I've had the same problem on some Dell and compaq system!Usually, it's because the cd used is a cdrw.... They often don't work with the liteons or the cdrom given with them. Sometimes, changing the firmware of the cdrom or the bios of the machine helps!! Anyway, also, create the cd in 4 X is more readeable too. MRmagic Posted by xoben on May 25 2004,04:40
There are two possible problems:1) Some CD/DVD-ROM devices cannot read CD-R/RW discs properly. This problem never occurs on CD-R/RW drives 2) Some very old Pentium systems do not support int 13/42h BIOS call, and a read error message will come out on boot screen.

xoben, thanks for your clear answer.I think your answer is in my case. the computers that don't boot from cd are old pentiums. then, isn't there any workout in old pentiums? Posted by mrmagic on May 25 2004,15:45
yes there is, it's Bootable CD Loader v1.50Z.A floppy that allow to load the cd on old pentium! < http://bootcd.narod.ru/index_e.htm > It might work for your case. mrmagic Posted by suwon235 on May 26 2004,10:30
