No, I did not try those parameters. I will seek to use them and then I will say if it works.

I saved two Windows ME/98SE boot images (one 1.44 MB and the other 2.88 MB), as boot.img in the custom folder. The SATA harddisk was available and enabled in BIOS options. UBCD did not properly boot the custom boot image. One of them had a menu like: 1. Boot from harddisk 2. Boot from CD-ROM The men...

I consulted the FAQ. There it says that if you want to access SATA drives, you have to set them in BIOS menu as pseudo-IDE drives. My motherboard does not have pseudo-IDE mode for SATA drives, that's why it gives problems when UBCD tries to access SATA drives. So, I think this is the big difference ...

Problem persists in UBCD 4.1.1. So, those boot disks fail to boot when: - SATA disk is present, *and*: - ATA boot ROM is enabled. This boils down to: if the BIOS/DOS is able to access the SATA drive, then those boot disks fail to boot. Normally, that SATA disk is seen as drive 80h (0x80). The option...

Maybe it comes a bit late, but I say it nevertheless: I was able to start UBCD 4.1.0 on that problematic computer, after I have removed that SATA drive from it. After putting the drive back in, it failed ...

Erf :( Then I have no idea what could cause it, sorry :/ Maybe Victor will know... Problem persists in UBCD version 4.1.0: LZ-DOS boot disk 4.30 fails to boot, mentioning: - InitDisk Invalid Opcode at 0074 D000 0046 2074 D800 0000 01FF 0100 5411 0000 0BA6 0000 0B96 Then, Ctrl-Alt-Del is able to reb...

Yes. It is up-to-date since a long time.

The following boot disks fail to boot, on a certain computer I have (they boot ok on the other): all DOS boot disks + Tom's Boot Disk (Linux) Therefore, except some motherboard programs, many programs do not start at all, since they rely upon loading DOS with all its drivers, and that fails. The err...
