Windows Forum / Windows 98 / Disks / File System / January 2004Fat32 USB MO Boot : Missing operating system
Hi, I'm attempting to get Windows 98 (original) to boot from a magneto optical drive (fujitsu DynaMO 640se (M2513EL)). This is a SCSI drive connected to USB. I'm attempting to use a 128MB disk formatted as Fat32. While booting, I get a "Missing operating system" error. I've created a Fat32 EBD (using the CD), and did an FDISK /MBR and SYS C: but I still get the error. If I try this with a Fat16 disk, I have don't have that problem. Any ideas? The BIOS handling of the boot device chain is the issue. In order to find the boot sector on your M2513EL, the BIOS would have to include routines to handle an SCSI translator via USB hub, assuming it contains enough code to handle all the necessary USB protocols (OHCI, UHCI, and maybe EHCI) Unless you opt for a boot sector on a garden variety device like a tiny hard disk or USB key, with a driver pointing to your M2513EL, it might be simpler for you to use a SCSI card with a built-in BIOS extension, which could handle the boot directly from the SCSI device (to be set-up in the SCSI card menu) . Note that you might have removability issues, where if you are paging on the magneto optical , you might be in "16-bit compatibility" mode. Besides the strain and latency associated with an optical drive [WIN9X involves millions of read/write), you might need a lock filter (software) to make the drive appear "fixed" to the operating system. Good luck, Chri |
